Strange sniper/ignition issue

[MonsterBIlly]

So I have a sniper. When I come to a stop I can be sitting at a light and ny tps will be 4 to 5 percent... weird idling...

However, I noticed that if I start it with key on from the solenoid rather than using the key, ths tips will always stay at 0 when idling.

I am getting some type of interference only when its started with the key? What am I missing. I am using a hei dizzy and have a single wire alt.

Is it possible there is still a resistor which may be interfering?

With the sniper on and the rig off, have you checked your throttle cable travel? TPS should read 0 without touching the pedal, and get to 85-100 on the floor.

The IAC will fluctuate but should read between 2-10 percent idling in neutral, per the holley instructions.

Where did you connect the pink wire? I started a thread on this when hooking mine up and there was some discussion regarding the best place to tie into to get power during cranking. I ended up using one of the accessory wire circuits with the painless harness, but several guys talked about wiring up a relay to provide a 'clean' 12V signal while cranking:
