need some help!!!

fired it this morning and she would barley run. the vacum gauge is reading like three pounds, she is stumbling like she has a HUGE cam in it. as soon as it revs up to like 1500 and above seen seems to run fine. she is also running lean at idle like 18-20:1. anything you guys can help me with. its starting to stump me cause i couldn't find i vacum leak, but going to look again tomorrow.

Id double check all the vaccum lines and boost lines etc. Make sure they are connected and even do a leak down test if possible. Sounds to me like its something simple like a vaccum line or the sort. Check for cracks in the lines too as simple as that may sound, some people look to see its connected and dont even bother checking for tears in the line itself.

yea ima check it with some starter fluid tomorrow, and see if i can find the leak that way. thought it might have been the timming jumping a tooth, but it wouldn't clear up when i revs up

Try looking at all your wiring to your injectors and spark plugs. Check the spark plugs to see if any of them have fouled out. Once you check them, look for signs of problems. Let them talk to you

Check your connectors on the MAF sensor, it sounds like when those come loose. Also check all hoses from turbo all the way to the intake. You can always take off the cam cover and rotate the engine to check the teeth in case it jumped.

If its not a boostleak, check your plugs, sparkplugs, coil pack and O2.

huh... what, from my understanding if you are running lean then you won't foul out any plugs. The electrodes and bridge will be white.

It really sounds like a vacuum leak. If you can, use propane instead of starting fluid. Its safer to use and yet great for finding leaks quickly.... Or a simple boost leak test will do....

to find vacuum leaks, i would turn the car on, get a can of carb cleaner or water and soap, look for bubbles with the soap, and increase rpm with carb cleaner,,,

Check to see if your BISS is still in the throttle body. Mine fell out and was idling a lot leaner than that even! The lope (insane) was a lot more than my BC272's could dream of.

Its gotta be a vacum leak if its that low...

I have had a couple of those come before. Now once I set my base idle I just insert a piece of rubber over top it. Worked like a charm...

Or, jumped timing.
