Re: intake problems Check to make sure that the throttle blade is closing all the way, if it's not then adjust the cable.

Re: intake problems tonite i am going to start by looking again at the tb, then i will look in to the maf. btu the thing i am worried about is that there is a plate that you can remove on the bottom of the intake to do more porting to it. well that plate has a gasket and that might be leaking but i dont really think it is. if all else fails i will pull it back off and reseal the inspection plate.

Re: intake problems try plugging the idle air control inlet with your finger or a rag and the car should alomst die. if it really does not change any the u got a vacuum leak some where. if plugging it and the car dies then the idle air control motor is not working properly.

Re: intake problems I would look very seriously at the bootom plate on the manifold. I have had trouble with it being to thin and flexing/bending between the bolts. i built a thicker plate and sealed it without the gasket (motorcycle case sealer), all is well now.
