Need help on 2,000 rpm idle and loping
Hi guys,
I had a coolant leak over the last week from the small "J" hose behind the intake plenum so I decided to take it apart and fix with a few other things.
I got everything back together and started it up, the only problem is the idle is sitting between 2,000 and 2,200! I took it for a drive around the block to see if it would straighten itself out, it didn't. When I pulled in to the driveway it was loping between 1,500 and 1,700.
Here is what I replaced during this project (BTW, it idled fine before):
Injector o-rings
Injector bushings
Fuel rail crush washers
Upper intake plenum gasket
Throttle body gasket
Small coolant hose by firewall
Coolant
Radiator cap
I must have done something wrong in the re-assembly but can't figure out what.
Any ideas would be much appreciated.
