Thread: im having a major issue with this car....

im having a major issue with my car here. i just bought this car a coupel days ago. The previous owner told me that he just did the timing belt and water pump and that ever since he did that, it idles like crap, and runs like crap when NOT under boost. Now i figured that the timing was off a little bit.

When you drive the car, and boost, it feels fine and pulls REAL good but once you are under vacuum or idle, it runs like crap. I pulled the spark plugs and wires cause i figured id need new ones anyways. when i pulled the #1 plug, the plug was all black. The rest of the plugs were fine though. I replaced them all with NGK BPR6ES plus and Autolite wires. it still runs like crap.

my question is this, i dont think the timing is off because of the #1 cylinder plug being black. Also my vacuum is never less that 10 and usually sits between 0 and 8 which i know is not good. What does this sound like to you?? ive checked every vacuum hose and they all seem fine. The only other thing i can think of is when it is idling, back by the intake manifold, it always sounds like theres an exhaust leak kind of sound and i dont think its the exhaust cause it doesnt sound like that when driving. Any help with this would be greatly appreciated.

Sounds to me like your exhaust cam is retarded back and off timing. People do this to sacrifice drivabilty and gain top-end power. I would realign your timing belt. As for the black spark plug, could mean a number of things. Black soot = rich, Black wetness = oil.

Is the bov recirculated?

yes the BOV is recirculated. it was black soot on the #1 spark plug. so you think its the exhaust cam??? do i hve to pull the belt off and realign the crank and the cams???
