My truck has been down for some time now, and this issue has gradually gotten worse. I start and run my truck once a week. I let it get to temp then shut it down.
When I rev my engine it revs fine but when it comes down it hesitates to go to idle, it stays at 1-1.2K then slowly goes down. It used to go right down to idle, but this started as a little thing, but now it does it longer. Any ideas?
FYI, the engine is a 93 w/ 93 ECU and wiring, not the original 94 SFI engine
This video might explain it better, you'll see it's up to temp.
