She\'s driving me nuts! Hesitation problems

[ianelvar]

Hello again!

After my saga with the CAS, and eventually getting her to run properly I\'ve now got boost problems.

She started to get a little shaky on the second turbo. Kinda jerky and hesitant.

All my rats nest pipes have been done, and cable tied very very tight..

I searches around, found the grounding problem, so I cleaned all my ground points, and added some more. This didn\'t help at all.

I found the thread about the fuel pump rewiring, and had a look at it. I took it for a drive to see what it was running at, and the car started to act like a bucking bronko! At the first sign of boost it behaves like the ignition has been turned off. Backing off again brings it back to normal. I can get it up to 5K as long as I keep it off boost, and very gentle on the throttle.

I did the pump mod, but it\'s not helped at all.

help

I\'ve looked at loads of posts on hesitation, but can\'t find anything that really matches my problem

Cheers guys

Check your plugs aren\'t knackered. Are you running stock boost levels ?

try resetting the ecu, by removing the negative terminal of the battery and pressing the brake pedal down for 30 seconds,  had a similar problem when my car was a twin and it solved the problem.

Cheers for the suggestions. I haven\'t looked at the plugs yet - should have thought of it really, but have done the ECU reset. Car is totally stock.

I suppose the problems with the CAS being faulty could have made a real mess of the plugs. At least it\'s something to go on!

Thanks again, I\'ll let you know how it goes

No joy with the ECU reset or plug change.

I pulled the ECU codes, no problems there.

I have a sneaking suspicion it\'s electrical gremlins. Any ideas?
I know the pump is getting a good supply now.

Quick update:

Won\'t go above 0.2 bar on the primary. It spools fine, then I\'d say it fuel cuts when it gets to 0.2 bar.
