I need some assistance here. Let me give you the run down of what I have going on..

Recently built up a 22re with lcengineerings's headers & downey intake, and the "Engnbldr 261 Cam . This is for a pickup with an AUTOMATIC transmission.


Issue #1: Timing:

The book says 5degrees btdc with check connector plugged.

We do this, and the truck idles nice, HOWEVER if we press the brake rpm is not steady and jumps up and down continuously. We checked for vac leaks. Could not find any.

We currently have it set at 5 degres btdc without the connector plugged and it runs _ok_.

Issue #2: Idle.

we have to idle around 1100rpm otherwise when we put the tranny in gear it stalls. Shouldn't the truck compensate?

Do you have suggestions?

Issue #3: TPS

Do you have suggestions on how to correctly set this? So we can verify our configuration

MAF has not been adjusted yet, as we do not believe it will help our idle issue.

Your sugestions regarding "MAF, "TPS", "IDLE", and "TIMING" would greatly be appreciated.
