HI Guys, i just having a few problems with my walky. it starts up o.k for bout a minute, then it loses it idle and then stalls, what could it be? i've changed plugs, leads, injectors and coil. it just sounds out of tune, is there any way i can tune it myself or does it have to on a dyno? help appreciated

maybe get it on a dyno at a performance shop - so they can pinpoint the problem?

Best to have it tuned on a dyno, with someone who has Kalmaker, the program to tune delco computers which the walky uses.... Dyno is far more than just a tool for measuring power. It's great for finding little problems throughout the rev range.....

Dyno is far more than just a tool for measuring power. It's great for finding little problems throughout the rev range..... there is a meter (some call it an idle motor) near the throttle bodies, I changed mine and it helped a lot.

TPS - on the throttle body - that what your talking about?

The two throttle bodies on the Walky don't have an idle air bypass like normal throttle bodies do. They use a separate valve for this. This would be the part that Walkie is referring to. Corsa

although I don't have a walky, my car runs the same EFI system. Does it stall when you are driving it, ie as soon as you put your foot on the clutch? I had this exact problem and was because the speed sensor kacked itself. You should eventually get a fault code from it. Put in a new sensor, prblem fixed immediately. Also, try cleaning out the throttle bodies. After a while they cake up with a bit of crap and may be restricting air flow at idle.
