Yeah, thats what I'd check next. My timing was way retarded and I had no missing or backfiring, so maybe Undisputed's timing is too far advanced.the converted wrote:Boro I figured you'd be the first one to say check your timing out of anyone. That's where I'd start.

thanks for the help man. i changed alot of my gaskets all the main ones( exhaust manifold gasket, 4 bolt turbo gasket, turbo arm gasket and both the downpipe gaskets but i will check for leaks does anyone have the link of the thread that showed how to check for boost leaks? i saw a while backboro drift wrote:Besides the plugs, I would do a boost leak test. My car was doing the same thing except at cruising speed (light to medium load) it would backfire and miss. Turned out I had a major vacuum leak.
What did the spark plug on that cylinder look like?Team_Undisputed wrote:the 2nd injector (counting from left to right) was the bad one i pop it out and there is a tiny puddle in the hole where it was before. and then i was inspecting the injector and it falls...FAIL... and the yellow plastic top breaks so i have to get a new injector now and do you guys think that could have been causing the problem the same thing had happened before. injector problem?
good point. Did you check your BOV for leaks as well? Anything that dumps air out of the system while you are at WOT will cause the problems you listed, especially under warmer temps.boro drift wrote:Besides the plugs, I would do a boost leak test.
