Hi, I'm new here and I'm having a problem with my 95 flair side 302 automatic. While driving it will randomly bog down, check engine light comes on and it pops back thru the intake, I pull over shut the key off and re start and all symptoms are gone, power is back check engine light is out all is well. I pulled codes KOEO Pass, KOER Pass, KEEP ALIVE 172, 556, 668. Any help is appreciated Thanks.

 

I'll be watching this too- (ironically) my 95 Flairside just started doing this as well. I'm sure it's not body specific though. When mine was bogging down and popping back through the air box, I just pumped the gas (then floor it) and it would clear. Only happens about once a week.

 

You have no active error codes at the time of testing, however your getting intermittant failures the qualified for continuous memory. #556 Fuel pump relay circuit failure (replace the relay), #172 o2 always lean(what is your o2 sensor setup & how old? 1 before the Cat,1 before the Cat, 1 after,2 before and 1after?)#668 Transmission circuit voltage above max range (not sure about that, my truck tranny it not ECU intigrated.)
