SOURCE: 2003 Silverado rough idle, idles good after "check engine" light

Check your o2 sensor voltage, those trucks are real bad for o2 sensors, and yes if one sensor is reading 0mv, the others will start to drop out, and the vehicle will run very, rough. You also may check fuel system pressure, should be almost 60p.s.i. If its alot lower, Id be looking into a fuel pump. If that vehicle is drive-by-wire (no throttle cable), the throttle bodies get very dirty and cause that concern also. Id start by having the vehicle scantested.

SOURCE: idel problem on 5.7 1995 silverado

You engine is TBI, It uses a MAP sensor check the vacuum line for crack and make sure yo have a good seal, The distributor also check and make sure the pick up does not have corrosion which causes the relutor to stick. As for the EGR it would cause a misfire, and yes the do fail. I am sticking with the IAC as a problem its a stepper motor and has a high failure rate, chack also the ECT (engine coolant temp sensor) for corrosion that gives false reading.

Pathfinder "cuts out" at 2,300 rpm


Replace your MAF, its a little pricey around $280.00 or so but this will clear the code but make sure you have the ECM reprogrammed to perform a "learning" sequence since sometimes the code will not clear even though the vehicle will run like new. This reprogramming will most likely have to be a dealer performed procedure.

CAR RUNS GREAT, STARTED DIEING WHEN A/C WAS TURNED ON, NOW A FEW DAYS LATER IT DIES EVEN WITHOUT A/C ON, RUNS BUT WILL NOT IDLE


CHECK IDLE SPEED SHOULD BE 650 - 850 RPM. IF IDLE TOO LOW AC WILL PUT DRAG SLOW DOWN ENGINE CAUSING ENGINE TO STALL IF IDLE SPEED IS TOO LOW.

what you realy need to do is check your fuel pressure. it sound like a fuel pressure regulator . but ive also seen a dirty fuel system and defective fuel pumps do the same thing.
