2002 Tahoe 5.3, under a load I get a multiple cylinder miss fire code. Engine has never stumbled or has a miss in it. This happens only when under a load like pulling my travel trailer. Driving down road and not under a load it is fine. It does have a bad O2 sensor I need to get taken care of but would that O2 sensor cause the multiple cylinder miss fire code? What else could be the problem. New plugs in it now. cy

1994 Ford E250 4.9L 92,000 miles. at idle and driving my engine seems to cut in and out sometimes just a little and sometimes it makes the whole truck buck when im driving. The codes point to EGR and throttle position sensor. When I unplug the sensor the rpms go up and the engine smooths out. Can that sensor cause my truck to do that? I wanted to know before I order one. Thanks

95 Mazda b2300 2.3: will a bad cam position an a bad crank position sensor make my truck not start? Also will a lil bit of oil on the cam position sensor cause it to go bad?


You seldom have both sensors fail at the same time.Either one could keep the truck from starting.You should have a trouble code for one of them if they have failed.As for fuel, do you know you are getting power to the pump ? ... Mazda B2300

One of the o2 sensors are bad on my 2003 silverado z71 (5.3) and my truck just started missing really bad, almost to the point where I cannot drive it. Could the bad o2 sensor cause this or could this be another problem? I also noticed that my temp. guage is not reading true, but is moving back and forth.

Does the turbo need to be removed to access the # 4,5 and 6 injectors? And can the P2285 code which says we need to replace the IPC sensor and pigtail cause the ford dealer to think the injectors were bad. Could there be a connection here because there is also a leak at the sensor? Truck only has 109,000 miles on it and seems strange that injectors (3) would suddenly go bad


If I was you since there is a leak I would change the sensor before I make any other repairs. They are all related to each other. If you lose your high oil pressure you will trip codes for injectors. I would fix the oil leak at the sensor first then ... 2004 Ford F250

I have a 2000 Ford Expedition Triton 5.4. I recently took it in to advance and had them check the codes. I said 3 out of 4 o2 sensors were bad. I got two of them changed and had to wait a couple of weeks before I could change the two upstream sensors. I have replaced all 4 but my truck is still running rough. not as rough as it was but still rough. This is a truck that I have had to nothing to but maintance. What could be causing it to still run rough?


Take it to a different parts store or go back to Advance. Autozone and Oreillys will also test it. Now that you have replaced some of the parts you may get a different reading.\012\012You can clean the MAF Sensor in the Air Intake with ... 2000 Ford Expedition

I've got a 2003 F150 5.4L with 114K. Recently had the 100K service done at about 105K (plugs & boots, fuel system flush, coolent flush, tranny flush). Wife left for grocery store and said truck was idleing rough then check engine light came on. Only codes are P0155 and P1151. Both relate to "bank 2 sensor 1" O2 sensor, but the 1151 code has alot of other things that can cause this code. From what I've read, a simple bad O2 sensor shouldn't affect drivability. So this worries me since the engine

I have a 2000 Audi TT front wheel drive. Within the last two months the engine has developed a lot of spatial vibration under load. I can feel it in the steering wheel, pedal and the whole front end. I have replaced the plugs, maf, coil packs, and coolant temperature sensor. Mechanic believes this to be linked to a bad wastegate actuator, but I think otherwise as I don't believe a bad turbo part can cause this annoying vibration. It has been suggested that possible wiring harness, throttle body,

I have a 1992 chevy 4x4 truck with a 4l80e transmission. Just got it rebuilt and put a shift kit in it. It will work when i first take off then it will drop overdrive after a couple miles. It comes up with a code 68 overdrive error. I unpluged the input sensor on the trans and I picked up overdrive again. Does that mean that sensor is bad or what could cause that?

My 1998 2.2 litre gmc sonoma it bringing up a frequent misfire code when hooked up to a computer...i changed plugs,wires,the fuel filter has been changed and 2 sensors as well...it takes a long time to get up to the speed linit due to loss of power...it revs up ok untill i hit 2.5 grand on the tachometer....any suggestions as to what may be causing my truck to run so bad?


Possible failed fuel injector if the code is for one cylinder only. Multiple cylinder misfires can be caused by low fuel press. Another possibility is a vacuum leak at intake runners. ... 1999 GMC Sonoma

I love my 1997 T&C but just turned 200,000 miles and it is starting to give me issues. We had a problem w/it just dying for no apparent reason, tried a few things and the last thing was a crankshaft sensor; so far so good on that. This past week it started running weird, at first bucking under a load, usually low speed up a hill, would usually clear up if you gave it some gas. Now, it's much worse and actually popping through the engine. Thought at first I may have gotten some bad gas, but

Why does it seem as if quite a few 2003 owners are having the same exact problems all at the same time? I have been getting the "reduced engine power" message, as well as the "service ride stability" message- both started about 2 weeks ago- I will have no acceleration, I can turn the truck off, and right back on- and it drives as if nothing is wrong? I know I have a bad O2 sensor, but would that be causing these messages to come up?


What I have seeing in the pass is TPS you'll need to scan truck computer and get data, more then likely TPS.Good luck ... 2003 GMC Yukon Denali
