i had a vacume leak once. the hissing was crazy, and the car ran like crap. i forgot to clean the UIM gasket off the LIM. caused a bit of a leak.

as far as rough idle that could be anything. i would start with plugs and wires, if cleaning the buttlerfly in the throttle body, and maf doesnt work. if you even have a miss its either plugs, wires, or coils. atleast thats been my experiance in the past 8 years and 100k + miles.

Too late on the t-stat. I replaced that, and the housing last week - along with my radiator, water pump, and hoses. I did the spark plugs and wires in June, so unless they were faulty from the start, those are ok. But, I will inspect them to be sure.

And I completely forgot about the ignition coil. I'll be working on the car again tomorrow. I'll let you know if any progress was made. Thanks, metal.

no problem man. :cheers:

also fyi if you do pull a coil there are (2) 5.5mm bolts. one on the front, and one on the back of the coil. i know 5.5mm sounds really dumb, and it is but thats what it is.

Alright. I did the cigar test and the issue was pleasantly simple. The lower lip of the air intake boot was not attached to the throttle body. That was on me. After I did that all day job last week, I was in a rush to put the car back together, and I didn't attach the boot properly. I'm a very happy man right now. I cleaned the throttle and MAF sensor just for good measure, though. :lol3:

yeah i think we've all over looked something simple when putting an engine back together. i forgot to put a plug wire back once. it ran like crap and totally freaked me out. glad it was simple.
