Coilpacks for sure.

Does it sound like a rexy?

I had a similar issue, where my car would cut out, like I was actualy hitting a wall if I gave it some, turns out my standard fuel pump was almost dead...

Coilpacks

evil weevil, when you say hitting a wall do you mean you'd push the accelerator and then all of a sudderen it would miss and sputter and the car would go no where...... like hitting a wall :S if so i think im having the same problem with fuel pump which may also lead to a few of my others problems.....

Sorry to hi jack your thread sleepy33

Yeah thats basically it mate!

Id give it a hit/take off - and yes, it would start to go and then all ofa sudden, nothing, Id back off and gently gently ease on throttle and would go agai, but run like shit.

Around same time I was at WSID and on gear changes it was splat and splurr everywhere and I could only manage 14.7 @ 97 on all 4 runs

Took it to uni group and turnsout that with my old Fuel cut defender and standard pump, the pump was almot dead and my car was leaning out in a major way.

Had a quick read through your other thread,

Sounds like you have what I had - get a new pump and see how you go or some how test the current one?
