Question about 2002 Chevrolet Tahoe

Open Question

Flashing service engine light which according to the manual is a miss fire code. We are getting a miss fire on # 8 cyclinder and have run a compression check which is good. We replaced the coil pack on # 8 and it did not solve the problem. My mechanic thinks it is an injector problem and has suggested a service called "Motor Vac" which is supposed to clean the injectors. I have had this done before on other vehicles and it really makes a difference. Ron

SOURCE: I own a 2000 Chevy express 3500, 5.7 L. Last year

try unplugging the mass air flow sensor and driving it,it will throw a code for that when unplugged but it could have an "in range" failure which will not set a code while plugged in,hope this helps,also..has it been tuned up? what type of plugs were installed? was a complete tune up done? u could also try removing an O2 sensor and see if your problem gets any better..it could be a plugged catalytic converter,good luck

I have a 2009 Chevy Silverado 1500 2wd pickup. The check engine light along with the service stabilitrak and traction control lights also came on. It runs rough at idle or low speed. Where do I start?


Have it check for DTC'S - diagnostic trouble codes . If the check engine light starts flashing , park it . The flashing check engine light is telling you there is a catalytic converter damaging miss fire happening . An they can be damaged very easy .

Engine light comes on and engine runs rough.


That's not a question

You have a check light on- got to
get codes set and diagnose that issue

Runs Rough--may be related,still have to
have diagnose and repair

If you do all your own work,

its a well known cause that if the motor is running really bad the tranny will **** or act bad your gonna have to find the problem with the miss firing cyclinders and fix it doing this make fix your tranny problems you can clear most computer codes by unhooking the battery for about 10 min and then start it and see if the engine light comes back on that will give you a new set of codes you will have to have them read and fix what they are.

2 4 6 8 cyclinders are missing code mulpitul miss fires cant figure out what it is new plugs and filter could it be low fuel pressure


could be a fuel pressure issue. could also be bad gas. sometime a plugs up cat will set these codes. does the truck run rough? seeing that it is only the even #"s would make me want to see what is in common with those cylinders. migt be a stretch to think fuel when it does not effect the odd #'s also. do you have any other info? any other codes?

I have a 2002 chevrolet blazer with a 4.3, 4dr, 4wd. Service engine soon light came on, took it to the auto part store to code it they said knock sensor, 02 sensor, low evap voltage or something close to...


No I don't think so, knock sensor only work under engine load, when sensor picks up a ping or knocking, it will adjust timing, o2 sensor could be bad, and will save you fuel mileage, but a miss will also give you an o2 sensor code, running rich, have him check for cylinder miss first.

I have a 1993 pontiac sunbird. the check engine light keeps coming on and going off. i checked oil, transmission fluid...they are fine. what could this be?


If the check engine light is flashing,you have a problem that can damage the converter.If it comes on steady while running it has set a code. You need to get a code reader or have someone with a scanner like your parts store check the coded.If it is flashing while running it may be a miss fire detected and you need to have it scanned before you damage the converters
