I fixed the notorious leak on the intake manifold, but now I have rough idle and the car runs rough like it's searching for a RPM range to idle at. We doubled and triple checked to make sure everything is hooked up properly. Has anyone ever experienced this problem? Thanks.

 

are you throwing any codes? almost sounds like the iac.

 

Maybe one of the intake gaskets slid down at the last second while you were putting the intake back on?

 

you have an intake leak somewhere, or something hooked up wrong

 

Might have a fuel injector cable on the wrong injector.

 

Most like something self-inflicted. Keep checking.

 

vacuum leak?

 

I hooked up a Tech2 and got two codes.
0018- Injector Circut
0064- bank 2 H02S lean exhaust indicated

While the car is running we've unhooked each injector and nothing happens in bank 2. We checked everything we unhooked

Any ideas? Thanks for the suggestions.

 

Check your injector fuses

 

Most likely you don't have one of the injector connectors on tight. Since the passenger side bank is indicating lean, look at the passenger side injectors first.

Generally, with sequential injection, you won't get a major miss if you hook the wires up to the wrong injectors, not much more than a minor roughness, particularly when the engine is cold. But its worth checking to make sure you put the correct numbered connector on the correct injector.

If you can't find a loose connector, check the pink wire in each harness connector for 12V (when measured to a good ground). Then with the harness connector off the injector, check for 12-15ohm resistance across the 2 injector pins.

 

just check fuses, all good

That's the first thing I checked, made sure I had the injectors lined up right.
I will go check the connectors and check the pink wires
thanks

 

ok I checked for 12 volts and all are working. I don't have a ohm meter. Any other suggestions? Thanks

 

We looked at it again today and checked the gaskets to make sure they sealed right, it appears the right side moved. We sprayed brake clean near the gasket and sure enough right out the exhaust. So it appears we found the problem, but there doesn't appear to have oil leaking from near the gasket. I figured there would be oil leaking near there.
