the brown car in my sig. early mpfi, ea82. used to work good, started runing lean, now it will run fine, till the engine starts to heat up. which is about 1.5 minutes. swapped the afm, does the same thing.
kinda idles, and when i throttle it, it sputters, and shoots small backfires out the intake, small enough to not be loud, but strong enough to slam the afm flapper shut, for a split second. im talkin bad enough, that i cant even move it from its parking spot.
codes arent helping.efi temp sensor maybe? culd i have slipped a tooth on my tight timing belts? doh!
i have 4 subarus, and the only one that runs is the one i havent touched. =[

my coolant temp sensor would make my car like that. they are cheap too, so it might be worth checking into.
