Hey everyone-
I have an L94 with the TSP 4.2 VVT Cam Kit installed. The problem is I can't get it to idle on its own without holding the pedal at about 1200 rpm and even then it surges. I've tried changing the Target Idle speed as well as the Final Idle Airflow minimum, and spark table as suggested in an HPT video. I purchased the PCM tune from TSP which is the one I've attached. I tried to contact them for some support but apparently "Casey" isn't doing that anymore and otherwise hasn't returned my call.
The problem is it starts well, even when its warm but it is flooding the engine with Fuel. Its way too rich and has an uncontrollable Idle because of it. I know this is a big cam but it should idle around 1000 RPM or so. I'm starting to wonder if I don't have another problem with this engine. It has 58 PSI fuel pressure and the other data is in the data log I attached. Hopefully someone can point me in the right direction.
a couple of side notes. When I first ran this engine it was winter time in IOWA so it actually idled on its own. But it was much colder then and had open headers and I only ran it for about 30 seconds since I didn't have the radiator hooked up yet. Now it has mufflers hooked up and won't idle at all.
Thanks in advance!
