Hey guys, I have a question to ask about my Civic.

The engine run smooth 90% of the time. In neutral, the engine revs very smoothly The hesitation mostly only happened after the CEL came on & when I'm driving. I already put a Chevron fuel cleaner & it's still bogging from time to time.

When I shut off the engine & turn it back on, the CEL light came off right away but after say driving about anywhere from 15-30 minutes, the CEL light came back on & the engine hesitate, it bogs too.

I don't have a scanner & this morning when I want to take it to the shop, the CEL light was off most of the time. Could it be a bad O2 sensor? Bad fuel pump & filter?

Thanks again

 

jump the ecu and see what code its throwing. is it a h22 in a civic? most likely it the egr code 14.

 

Thanks for the quick reply but it's not an H22 powered Civic. My name is HondaH22A because I also have a BB6 Prelude.

The Civic is a 1993 sedan with almost 200,000 miles & a manual transmission. The engine is still the stock D15 engine.

 

Anyone else have any suggestion?

Thanks a lot guys
