Lately I have been experiencing a lot of engine surging, it happens when I am idle and when I accelerate.. Engine seerms to be a lot less responsive.. I been using 91 Oct the past two weeks just to clean the engine out.. But also recently installed E3 spark plugs. But never noticed it before, but I have been gone for the past two months. So I dint remember, just curious if you guys think it could be the gas causing the problem?

 

Personally I would never use those E3 plugs. Get the AC Delco plugs that the car comes from factory with. If I had to guess, its the E3 plugs. Could also be a vac leak, TPS, MAF etc you have to troubleshoot.

 

Picked up a new set of NGK G-Power plugs and throttle body cleaner... hopefully these fix the problem!

 

Go easy with the TB cleaner if your not careful you can mess up the TPS.

 

The tps is not near where your spraying so dont worry about this. Its in the t/b but not in the inlet.

Clean your maf too.

 

Changed the plugs and waited a few days to see if the problems would come back, and nothing! It was those damn E3 plugs! Last time I use anything other then NGK! Also cleaned of TB this morning and that seemed to help the throttle response too.. But the main problem was those damn plugs!
