idle fluctuating

[sarmientor]

98 v6 j30a1 bought it 3 weeks ago it was running fine, today I did a valve adjustment and cleaned egr port, pretty gummed up, after I put back together I started it up and the idle started fluctuating like crazy Idk if the v6 even has a bleeder valve to bleed the cooling system can someone help me figure out why this is happening pls

rpms we're jumping up and down? sounds like a vacuum leak, usually id say leak or IACV but you just rebuilt all that stuff so im guessing leak, did you replace the EGR gasket?

Any gaskets you took off, were possibly not put together as needed. Personally i use the rule of thumb that if i take a gasket off, i'll just replace it with a new one as 99.9% of times they were rather quite cheap even at the dealer.

I replaced the egr gasket and th gasket I did not replaced the intake manifold gasket but isade of metal so I didn't see a point to replacing it

the IM plenum gasket, its not that pricy, but it is important, its possible you have a leak there, take a can of carb cleaner and spray it all along the gaskets you removed and if you hear the engine pick up in rpms youve found the leak. i put a TB gasket on backwards and had the same symptom

Turn on the car and go around and tighten all of the bolts/nuts that you removed. The same thing happened to me twice and the first time I just tightened the Intake mani bolts and the rpms lowered. Air was getting in.

The second time it happened:

I just read from the link the issue that you experienced and I'm starting to believe it was in fact the computer relearning how to breathe what caused the idle to fluctuate after I cleaned up the gummed up egr port
