    I just put performance pulstar spark plugs and wires in about a month or 2 ago and ever since my light comes on and off my mechanic said the readout was showing a misfire. They tightened the spark plugs cleared the code no more than 10 minutes later it came right back on he then tells me it could be my dual cone cold air intake but the light didnt come on till after i put the plugs in. My other mechanic believes it could be my fuel injector or gas cap. Changed the gas cap light still come on and off at intervals. Turns off during full tank 3/4 tank 1/2 tank and 1/4 tank. Tried using fuel injector cleaners still comes on and off. Not sure what the problem is if anyones got the answer please let me know i love the car but this light is just pissing me off

You need to go to an electronic specialist or you can buy one of the scanners that clears the codes for you from advanced auto or autozone or some place like that.

Had a po102 code on a 2002 3800 engine chevy check voltage at 12 volts.cleaned sensor. reset code now it says po102 pd with no engine,but engine stalls when driving


HI, The DTC set PO102 is for your MAF (mass air flow) sensor. this sensors measures the air moving past it my heating a fine wire much like one inside a light bulb. Even cleaning these will not get the contaminates off. That little wire gets very hot and if dirt gets on it it will bake to it then this throws off its readings for your computer. If you checked and you have your 5 volt reference for this sensor the only other thing is to replace it. You can get re-manufactured one now at any major parts store. Good luck

CODE PO102 after Mass Air Flow Sensor replaced


Most faultcodes don't disappear automaticly, the have to be 'reset' manually after repairing. It sounds like the code didn't get erased after replacing the MAF. You could try to disconnect the battery for 10 minutes (disconnect and reconnect the negative (-) pole), which should erase the code.

Whenever the engine light still comes back on after that, there probably still is some (other) problem ...

2002 chevy impla v6 esngine 3800 check engine light is on, codes read po102 what does this mean


Code p0102, on either the 3.4 or 3.8 (3800) v6 engine is a problem in the Mass Air Flow sensor (MAF). If any work has been done to it just prior to this code, then you need to make sure the air cleaner, duct work, breather tubes, etc. are properly connected and not loose. If that is OK, then may have a bad, or dirty sensor.
