I have heard that alot of people say that it is the intake gaskets and i have heard people say that they have changed them and they still had the same problem so i am not sure. I have put on the new Mass airflow sensor and that has helped some. The engine seems to run better(no surging) other than the idle seems to be too high now and i get a jerking(bang) when it shifts when i slow down to 40km's or from stop to acceleration at 40km's.Maybe TPS? Engine still has a bit of a miss. I have found that the air temp sensor has a peice broken off the bottom so that may also be the problem. It's cheap so that is what i will try next. If this doesnt work then i guess i will have to try the intake and hope for the best. Ill keep everyone posted. Thanks for all the input. <img src="/forums/images/graemlins/cheers.gif" alt="" />
