Epstein.... U seem knowledgeble, would u like to earn some money by figuring this thing out for me? I looked for vacuum leaks today, couldnt really find one. I didnt spray it w/ carb spray, so I didnt check that good. I unplugged the mafs and the bastard started Idleing smooth - I dont know if thats because by unplugging the mafs, the idle was raised about 200 rpms? I need help!

 

could it be a idle air control valve? or possibly a bad coil pack, have you tried testing the coil packs to make sure that they are at the correct voltage?

 

You're obviously not to knowledgeable when it comes to troubleshooting. Go by the basic diagnostic steps...if theres a miss, is there a miss all the time? only at idle? only at a certain RPM? Unplug each injector (one at a time at idle) and if the idle drops or sputters, that is normal, if it stays the same then you know that injector is malfunctioning, then check if its actuating etc, do the same thing with the ignition system, if you give me $50 i'll tell you exactly what the problem is.

 

if it runs good with the maf unplugged, that would make me think it was a leak after the maf or th maf was bad. The maf is prolly good tho since it works fine at WOT. Seal your bov. Honestly tho, you paid for a swap. take it to whoever you paid to swap in a good running motor...

 

I appreciate the offer, but I am too busy with my #1 and #2 jobs!

I'll bet your bov is leaking at idle. Try unplugging the vacuum line from the bov and then cap the line off.

 

Go to home depot and get the following parts:
-PVC pipe end
-coupler with 2 clamps
-JB quik (or regular JB weld but i prefer quik)
-tire valvestem (you can get this for free if you know of any tire places or friends with junk drawers. if not go to wallmart.)


Borrow someones drill and make a hole in the middle of the pipe end. JB weld in the valve stem. then clamp the pipe end to one end of the coupler. JB weld around the seal. After this dries take off your intake pipe attach your new "pressure tester" to your turbo. have a soap and water mix and spray ALL of your intercooler piping where there could be a leak. With the car off use an air compressor to charge the tester. Have someone watch your boost guage to make sure you dont go to high (i always test to about 5 psi higher than i run the car at. If you have a leak the guage will either not charge or will drop off. the leak SHOULD bubble from the soap and water mix. Im not saying that you DO have a leak but this way you could find out for sure.

I know that people are now thinking , "wow this freakin guy is an idiot with ghetto ideas" , but it will work and it's cheap. That would eliminate the possibility that you have a leak. Not to mention fixing boost leaks even if they are small will make your car faster.

Please no haters. it is ghetto but it works
