OK, all of a sudden, tib was working pretty good, and then i got up last morning to drive it.. I had just reset my ECU to try and fix a lean issue that i was having..

anyways, i start my car up, and the first couple times it idles high and then dies.. the third time i started it it idled great.. btwn 14.6-15.10 on the wideband. so i was happy.. i gave it about 2-5% throttle to get the revs up a bit.. seemed good. minute i gave anything more for the throttle, it choked, read LEAN on wideband, and idled low for a sec and died.. what could cause this problem, without changing any settings? fuel injectors? pump?

i checked my TPS voltage.. closed i was reading 0.42v which is withing spec, and wide open i was reading 4.37v..

at idle the MAF was at 0.90-0.92v @ 830-850 rpms

i suspected maybe the o2 sensor, so i un plugged it.. still did the same thing..

throttle cable is fine, and the TB opens freely.

my vac. is also good and is reading 20in vac at idle..

maybe got some bad fuel??

 

ahh that kinda makes sense.. weird but kinda does.. i usually have the problems when its cold out.. weird why that would happen. i will try this tommorow.. seemed like an engine stall problem though. cuz when i had the voltages too high it had same symptoms..
