\015 Check engine light is on, i was told it was an manifold idle actuator. it is just not running smoothly, at idle or in motion. had a tune up about 8 months ago. is this something i can do myself, or does it require a mechanic?\015 Posted / edited by AnonymousUser on : 15-01-2018

Answers :

Take a can of carb spray spray it down behind the power steering pump at the front of the plastic intake if the idle picks up and smooths out pull the pump but you can leave the lines connected ,once that is done there is a plastic plug in the manifold which has a shaft and bushing behind it , the plug often pops out or leaks make sure the shaft bushing is there clean up the whole and the plug and jb weld the plug back in making sure not to get it into the shaft and bushing then jb the outside also check the manifold runners i jb welded all seams on mine since they tend to seperate or crack did this 2 years ago and has ran perfect sorry for the long post just wanted to be therogh hope helps.
I would look for vacuum leaks before I did any parts changing

It should have a code stored. Some places still carry the scanners for OBD 1 Fords for around fifty bucks. Without knowing anything else about the truck or what codes you have, it sounds like you have a bad throttle position sensor. ... 1994 Ford Ranger Supercab

I have a motor home with a 2000 Ford V!0. It runs beautifully until about a week ago. Cruising down the highway at 60 MPH and the engine shuts down. I put the vehicle in neutral and the engine starts right up. Another 50 or so miles and dit does the sme thing. Yesterday I drove it to the Ford dealership, about 10 miles, and it did it 4 times. Ignition is still on becase all accessories are working. Fuel pump is working because it starts right up. Don Westerhoff [email protected]

We have a 1998 Ford Windstar with a 3.8 liter engine in it with roughly 240,000 miles on it. The van has never really gave us much trouble. About a year ago we had the egr sensor, egr valve and ports cleaned because it was running rough. After we left the Ford garage about 15 miles down the road the check engine light came on. So we took it right back down for them to reset it again. They stated that since we replaced 1 oxygen sensor that one of the other 3 (cause there are 4 of them) is going b


My 95 ford windstar had over 300 k on it before i sold it. two things that may have been are are consistent problems with them are relays in the fuse panel under the dash and the EGR module failing which causes the light to go on. if the light went ... Ford Windstar

Have a 2000 ford ranger manual transmission truck used, after driving it 5 miles, going from 2 nd 3rd gears, it makes a grinding sound, even if you just ease into it, like a skip, then a grind. The engine check light came on after 30m to 60 miles after i drove it off the used lot, I took it back, they had their mechanic fix the chck engine light, 2 days later the light came back on, im wondering if the transmission needs to be serviced, I took it to "Ford" they did a quick analysis on it, somet

I HAV EA 2002 FORD EXPLOYER. IT'S MAKING A TICKING NOICE FROM UNDER NEATH. 1 MECHANIC LISTENED AND LOOKED BRIEFLY SAID IT'S INSIDE THE ENGINE. HE SAYS THE FORDS THIS YEAR DO HAVE ENGINE FAILURE AND ENGINES NEED TO BE REPLACED. IT HAS 137,000. I SHOULD GET MORE MILES OFF THIS ENGINE.


Ticking is usually from the rocker arms either sticking or wearing out. These parts need a constant suppy of oil to keep them going. You may have sludge built up in your engine causing this. My reccomendation is to bring it to a garage that can do a ... 2002 Ford Explorer

Oil consumption my 2002 ford f-150 uses about 1 quart of oil for every 3,000 miles. About 2,000 miles ago, when I would remove the oil fill cap with the engine running, the truck would go to a low idle and eventually just shut off. Now if I remove the oil cap, the engine immediatly just shuts off. I have tried this with the engine cold and hot, does the same thing. I have tried to add engine restore on an oil change but does not help. Any ideas???


They say that that is normal to burn some oil. I use Moble 1 full synethic oil, and it quit using oil, because synethic will not burn. ... 2005 Ford F-150

98 buick lesabre oil pressure dropped to 0 and engine died. added 1 quart oil, waited 30 minutes, started and drove 5 miles then oil pressure dropped to 0 and engine died. does this sound like a bad oil pump? where is the oil pump and is it hard to change for a "handy" person? thank you.


My sister had the same problem. There are 2 sensors that can cause this when they go bad. One is the oil pressure switch, which is located near the oil filter. When the PCM reads this switch, and gets a low reading, it will automatically kill the eng ... 1998 Buick LeSabre

A 2008 Ford Ranger 2.3 lt with a wobble in the fan clutch shaft and it only has 81k mile on it. It comes with a 875.00 price tag to have repaired.why would this happen on a engine that the first tuneup is 100k. The dealership said they have never seen this on such a young engine. I think Ford missed something in the making of this.

OK, here we go. Ford F150 5.4L 3 Valve - 90K miles - so far all work done at Ford Dealer Engine was indicating rich on ECL codes after a spark plug change for a lean. Initially spark plug change yielded a lean condition, changed plug on #3 again - went to a rich condition. All this on bank #1. 20 hours of dealer diagnostics - finally yielded broken roller lifter on #3 intake, replace roller lifer and cam itself on bank one. Now runs nicely at speed, but intermittently engine drops

1990 ford bronco 351 windsor engine, e40d at transmission. Drove on hwy at hwy speed for 2.5 hrs, turned off and engine started to sputter and pop with very low idle rpm. Shortly idle went to 0 rpm and engine stopped runing, 1 hour afterwards engine started up and ran normall next day also. What is problem?


I have an 89 with a 351w. Mine did the same thing. Sounds like its vapor locking. After you let it sit for an hour or so it should start up but you should take the EGR valve off and either replace it or clean it with carb. cleaner. That should el ... 1990 Ford Bronco

2000 Ford Taurus 110, 560 miles (original engine, rebuilt tranny) - #1 Problem: A few times a week when i come to a stop, the engine oil light will blink rapidly. When i speed up, the engine oil light will turn off. It doesn't happen everytime i drive. #2 Problem: I get a chirping sound almost when i drive. The faster i drive, the faster the sound. I'm not sure if a belt loose or not. I had one replaced after the sound started but it didn't fix the noise.


Sounds like a cam chirping, cant remember if that was normal for that engine, mine did it randomly, oil light could be a bad pressure sensor, hopefully it isnt your bearings wearing out, good luck i hated this car ... 2000 Ford Taurus

I have a ford ranger 2.5 TD 2003 only done 2,800 miles. when starting engine from cold there is knocking from the front which goes when engine gets warm. do not think it is the viscous coupling as there is no movement on the fan and fan stops when engine is switched off could it be the water pump bearing ?

Just bought a 2005 Ford Taurus with 68,000 miles on it and it sent 3 codes until the seller replaced two O2 sensors and turned off the check engine light. After about 3 cranks, the check engine light came on again with the code PO430 Catalyst efficiency low-bank 2. 1) What do you think the problem is? If you do not know, what things would you check in what order to diagnose the problem. I'm sure the seller doesn't want to hear that it's a bad catalytic converter and I sense will dodge that o

My 2004 Ford Ranger XLT 4WD 4.0 L V6 automatic transmission will develop a bad engine miss about 2 minutes after it is started for about 30 seconds and then will run just perfectly after that. It does this every time it is allowed to cool off for several hours. The Check Engine Light has never come on during this. The light does work though. It has 30,000 miles. It has done this for awhile (6 months) but seems to be getting worse.
