is there any idle problems at idle? or just when holding steady at 3k?

What about maybe a vaccum leak around the injectors....could that cause this?

slammin86

No problems at idle....it idles perfectly.....but when i try to hold the revs between 2000 and 4000 rpm, its like it cuts out every few seconds

slammin86

could this maybe a fuel pressure problem?

are you running the correct ecu? is your ignition system up to par?

Is it just on your tach that it does this, or can you feel/hear the engine dropping? If you can actually feel the engine dropping, you'd probably get better help from the FI forum. Otherwise you may just not be running enough power to the tach (wiring too thin/worn out).

I can feel and hear the engine dropping
