Dies when clutch is pressed in
I am totally stumped here!!
I have a Jeep with a SBC 327, mild/decent cam, manual trans, and a Holley Commander 950 TBI system. I run a full exhaust with a Catalytic converter as well as an HEI.
It was running just fine for a long time, (I just got this from a friend). Suddenly it started to die when disengaging the clutch to slow down.
- I changed the fuel filter and flushed the fuel lines w/ compressed air(thought it wasn't getting gas).
- Changed the ENTIRE ignition system (it was old and wanted to upgrade, plus I wnated to esure it was in good working order).
- I had the Holley ECU reflashed (my laptop wouldn't connect to it, firmware/software issues).
- I drained the fuel tank and refilled with fresh gas (thought there may have been water in it or just been bad gas).
It first started when I was about 45 minutes from home...it seemed to be OK on the trip back home...over time it got so bad I could only go about five minutes down the road...now I can't even get to the end of the block!!
Only thing that comes to mind right now is the Cat may be plugged or something...can't imagine why though. There seems to be plenty of fuel pressure at the TBI, I don't have a way to check it though.
Anyone have any other ideas...maybe experience with the Commander 950...Any help would be greatly appreciated!!!
