i just did a 2v to 4v swap and the past owner removed the egr vacuum lines off the egr vacuum regulator and didnt give me the lines! and that regulator bolts to the iac so im thinking thats why i cant keep this car running could you tell me where the lines go from the regulator the egr is diabled

[STSVT]

one line goes to a manifold vac. source ( should be the one closest to the electrical connector if i remember right) and the other to the valve of course. the car should run fine with the egr vacuum unhooked though. just curious, did your swap include the 4V injectors too? if so that might be your problem. the Cobra 4V injectors are 24lb/hr ( blue top ) vs the stock 2V 19lb/hr ( orange top ) injectors. If that's the case then you will need a mass air meter for 24lb injectors, or a stock Cobra meter, or a custom tune.

hope that helps...
