Hmm.
Ever since last week or whenever I've been having problems.. My FPR is nuts (it seems as though everyone's is).. Lately I've been having major troubles in the idle-3k range on the tach.. When idling at a light after driving, it wants to go down to about 100-200 RPM and almost die.. I have to gas it for about 5-10 seconds for it to get back up to par.. And then when I'm driving in the lower rpms, it's all jerky/hesitating, and just kinda rough.. at one point it was like driving in first gear without enough gas, just jerking really hard.. Anyone have any clue?? Am I rich, lean, or neither?? My idle FPR is anywhere from 40-55.. I reset the ECU to see if it needed to just figure out itself again and that didnt help either.. so I have no clue.

i have the same problem...and when u hit boost its ok, at least for me. but until then its all bogging down and fallin on its face unless u are really light on the pedal. i don;t get it. and i have new plugs, wires, o2 sensor, and cleaned t.b., so i know its not that stuff. any ideas?

Yep, it's ok at boost (i hope).. When I'm trying to creep home late at night at low rpm's its almost dying.. I have no clue what it is.. Does anyone??

Would switching to the Vortech S-FMU maybe fix all?

Check plug gap. I tried running .028 (turbo ngk-bkr7e) and the idle stumbled and dropped rpm's at a stoplight. Gap should be .030-.035 Also maybe check for exhaust leaks.

Oh, and around 30-40psi idle fuel pressure causes my engine to stumble & stall. Gotta be at least 45psi for mine to idle normally.

Anything above 45-50 would make it make poo noises (very descriptive huh).. but it fixed itself, the problem was that F'ing Gumout fuel system cleaner.. It (i'm assuming) released a ton of crap (30,000 miles worth) into my fuel lines, pump, etc.. and it took 100 miles of driving tonight and some nice sunoco 94 octane to clear it out.. now the only noticeable problem from before is that the A/F meter isnt working 100% right.. but I'll take that over sputtery, jerky, headacheness anyday
