i have a 91 integra ls. i got brand new ngk spark plugs put them in. week later the car wouldnt start it would just turn over, took the plugs out and they was filled. put new ones in it started then a week later they got filled. its dumping to much gas and its filling my plugs, the guy at the honda shop said the water sending unit it bad so its saying the car is cold so its sendin more gas. i put a new one in and its not changed. any ideas?

 

So are you flooding the cyls ? STOP doing that you'll "wash the walls" (lower comp). do you have an adjustable FPR or aftermarket injectors or fuel pump ?

 

everything is stock. besides supsenion and wheels.

 

Have you checked that the oem regulator is working fine?

 

nope i didnt think about that. it has the check engine light on and throwing a code 15. honda shop told me to check the tempuature sending unit.

 

Might help you out some.
