I just installed the XE 224/230 cam this past weekend. I know it requires tuning but this is what has happened so far....The guy did a little tuning tonight and didnt get much accomplished. He thinks theres a vacuum leak because the maps were high at low rpms and idle. When more throttle was applied it read normal. Before tuning my car would almost cut off at idle. The rpms would drop then stabilize. Well, he fixed that, but before I left he did another change and now my idle sucks again. He didnt have time to ride in the car and get some WOT runs to work out all the bugs. Hopefully he can do it this weekend. The car also kinda bucks if the gear im in isata to low of a rpm! Any suggestions?


I know this isnt serious to some but I need serious answers as to what the problem may be. The car was tuned by pcmforless before. I know they are notorious for setting the pretty lean. The maps were way off and the advanced timing was jumping all around. He did get rid of knock but thats it.

 

Please post general troubleshooting in a general tech forum. Since you have this in the appropriate forum already (LT1 Tech), i will close this.

Thanks.
