hi everyone!
i've been slowly working the bugs out of my car, and that's thanks to you all!
this issue isn't a major problem but maybe there's a fix...my car starts fine and idles ok in the am, but if you try to gas it, or move it at all, it will die. you have to let it warm up a bit, even on nice days. the computer isn't giving codes, so i looked at the cold air intake after reading about those on here. don't see any holes or vacum leaks. the maf seems to be new, but i checked it for dirt and bugs too. if you're in a hurry and don't give the car the warm up time, it will buck and jump when you start letting the clutch out. anyone have any ideas?

i remember like a year ago my car was giving the same symptoms, and i found that my problem was a vacuum leak; have you tried using intake/brake cleaner around the clamps & hoses?

hey thanks,
sorry so long getting back..been outta town awhile.
i'll try that. the car also threw a code a couple days ago, po171. pretty sure its a lean code. bet you're right about vacum!
