Answers :

Leaving the gas cap off can make the warning light come on. You would need to have the computer scanned for trouble codes next.
And if the truck stopped before you replaced the pads, I doubt replacing the master cylinder will fix the stopping problem.

I had a mechanic test my vechicle because my check engine light was on. he came up with a code P0441: which he wrote down for me: EVAP emission Control System Purge Flow Fault.

I have had a Check Engine Light on my dash for a good 3 weeks. I noticed the Van running really ruff. I took the van to autozone and got the codes ran. The code of P0303 (cylinder 3 misfire) came back originally so I changed the plugs and it fixed the problem. About 1 week later I got a check Engine light again. I then again got the codes ran and this time it came back P0304 (cylinder 4 misfire). I then changed the plugs again, a day later the light came back so I changed the wires. Then a day a


I agree with phillyboy. Don't buy a compression gauge though. Pay a garage to check your compression. $40 or so.There are three rings on a piston, a compression ring, an oil ring and another compression ring. If your rings have failed on cylinder 4, ... 2001 Dodge Caravan

I have a 3.1 liter 6 cylinder automatic chevy malibu with error code P0741 Torque clutch converter solenoid circuit (performance or stuck off). I had it initially diagnosed, and the engine light went away for 3 days, then came back, so I made an appt. with a mechanic, and 3 days later, the light turned off by itself (before I gave it to the mechanic). He said it was locking up perfectly fine, and everything was running perfectly smoothly. On my way home (after they had closed) I received the eng

Two-fold problem: (1) Check engine light would come on when I was low on fuel. After refueling, it would go away. Eventually it came on and stayed on so I took it to the shop. They said it needed an emission vapor canister. However, after that day the check engine light didn't come on for months so I didn't get the canister. Eventually check engine came back on, I took the car in and got the new vapor canister ($350). Three weeks later the check engine light was back on when I was low on

1997 Toyota rav4 Had serpentine belt and timing belt changed and all gaskets on engine, was hit on left driver side front fender on the way home and my check engine light came on. I'm told the hit didn't cause the light to come on. Flush was done on the egr system and vacuum modulator replaced. Light came back on a couple days later. Mechanic can't figure out what is wrong, light was off for a couple of weeks and just came back on.


If its the same code it should be fairly easy to see if the EGR valve is functioning correctly. Its vacuum operated so with the engine running you can apply vacuum to the solenoid and expect the engine to run extremely bad if not stall. If it does th ... 1997 Toyota RAV4

Always had a problem with 2006 grand prix GXP 5.3L V8 "using" lots of oil. This weekend check engine light came on, tech told me it was an oil pressure error. Added about 1.5 pints, reset the code, but it came back on later in the day. Hubby took it back in, resest the code , but light came back on. Tech said its either the oil pressure sensor or the oil pump. Engine is NOT knocking or sounding like its about to break down...how do i know what the problem is? I can't afford to fix both...

I have a 94 pontiac bonneville and the last 2 days when I'm stopped at a light and I start to drive again my car goes really slow then kindof jerks to catch up. I just bought the car 2 weeks ago and my check engine soon light came on. I just did an oil change but my service light is still on. I have to get a smog within 30 days but I need to get the engine light off. I have also disconnected the negative battery and the light came back on a minute later. What could this be?

I have 1998 Nissan Frontier with an engine light on. I paid a mechanic to put in a speed sensor and the light came back on the day after he put in the new part. The codes before he worked on the truck were po500 and po325 and the codes are still coming up po500 and po325.He told me he did not replace the knock sensor. I don't know what to do next. I paid him and passed emmissions but the engine light came right back on.


The PO 325 code is for VSS vichicle speed sensor and PO500 is for a knock sensor,so you will need to see what the new code is to be able to help you, the engine power manegment is controled by both get it scanned by autozone or the mechanic that did ... 1998 Nissan Frontier

The car failed Emissions test. It was discovered the Oxygen Sensor Circuit - DTC 44 (code) was defective. When the ECM was replaced, the car passed Emissions testing. I drove the car home and then to work the next day which was a total of 14 miles. When I was ready to turn the car off, the check engine light came back on. I brought the car back and the ECM had to be replace again. Once again, home and to work (14 miles) and the check engine light came back on. The ECM has to be replace ag

My check engine light came on the day after I had my car smog checked. My Tech noted error codes po136, po174, po303 and po305, It's a 2002 Highlander with only13,660 miles on it. Toyota had it for a week and couldn't resolve the problem. They reset the check engine light and told me to keep driving it. The light came back on after 7 days. Any suggestions?

Engine light came on about 5 days ago, took it to a mechanic who turned light off, but it came back on later that day. went back to mechanic and he plugged his machine up and said a code came up indicating that i needed to have the transmission taken apart to diagnose problem. he asked if i had any problems the car shifting when i drive. and i have not had any problems. he said i could probably wait until something does happen cuz it could just be something as simple as a sensor, etc what do u r


I would consult a good transmission repair shop or a Dealership and get there opinion on the code that is coming up, if there is a real problem, it may be a simple fix, but if let go, it could possibly cause some real damage. Did he give you the code ... 2001 Chrysler LHS

I have a 2002 Pontiac Grand Prix GTP. One and a hlaf years ago had the MAF & EGR valve replaced, 1 month later another MAF put in. Two weeks ago I had MAF put in as engine light came on, drove 20 miles and it shut off. Had it towed as it would start and shut right off again and they said it was a defective MAF...again. Engine light came back on next day and it ws the intake manifold & gasket...had them replaced. Engine light came on yesterday on my way home, I made one stop and could not g


Hi Dawn.I don't believe that your MAF has ever been the root cause of the problem to begin with. They don't often fail on their own and especially after only a month. If it is due to an electronic problem then it will be instant. The o ... 2002 Pontiac Grand Prix

I have a 97 chevy tahoe. I changed the spark plugs, wires, distrubutor cap, rotor. About 300 miles later engine light came on. I thought maybe cheap distrubutor cap and rotor was cheap. I went to auto zone and got another one. Engine light came off on free way. Came back on later on that day. I checked compression test was good. Only miss fire on cylinder 6. So I changed plug and wires again. Still engine light is on. You can on tell the miss fire when your at a stop sign or going slow. Also I
