I have a Walboro fuel pump and a Petit ECU along with a list of other mods . All of a sudden i have a stutter if i am driving under 3000 RPM and lightly ease into the throttle . I really only notice it in traffic . What is wrong with my car and how do i fix it ?????? Is it my fuel pump ? My ECU ? Or the fuel pump transition between 6 volts and 12 volts that i have read about ? Any advice would be greatly appriciated .

 

ahem *search* cough cough....

Here's what my problem was, and how I fixed it. It doesn't work for everyone, but start with the easy stuff and go from there.

Just be sure to read the ENTIRE thread before you ask any other questions...it's 3 pages, and should cover everything. If this doesn't fix your problem, do more searches. I spent 3 days searching under different terms before I found what I wanted!

 

I am going to redo all of my ground straps this week . 1 BAD 7 , Thank you very much for posting that thred for me . Sorry i didny search , I didnt really know where to start .

 

no problem...I just sat down and thought of every way I could describe the problem, then searched for each word

I don't mind helping out; rather than jumping down your throat like some people on here (which is why I mentioned searching ), I'd just as soon answer your question. If you're desperate or in a hurry, asking is usually a LOT faster than searching, especially for a quirky problem like this.
