slight idle issue after exhaust manifold replacement
Hey everyone, my first post and I'm asking questions already.......sorry, I apologize in advance!
I changed out the exhaust manifold yesterday because it was cracked and was driving me nuts. Now its idling around 850-900 when in park.....now this is driving me nuts. I know its real easy to get sloppy or careless on this job which can and will lead to a leak however so slight and cause an idle issue but I'm pretty sure I was extremely careful and paid attention to detail when doing the job because of this.
I bought one of the $99 ebay manifolds, used a mopar gasket, cleaned the block and intake to perfection, sprayed the gasket with copper, made sure the maifold was seated on the dowls, torqued the bolts in proper sequence to approx. 23-24 ft. lbs, re-connected everything as it was, cleaned the TB and replaced 4 of the six injector o-rings. Vacum lines look good, I've sprayed the intake with cleaner while its running to check for a leak.......got nothing noticable. The only thing I can think of was I reused the TB gasket because it was fairly new and looked great ???..........any thoughts or ideas guys are greatly appreciated.
