Tammy had this crazy problem... random stalling!
The usual failure mode of stalling are the following:
1. No fuel
if you have no fuel, you need to check the filter if its blocking it due to too much dirt in filter. if its not the filter check the pump, does it deliver fuel? its not then that's the culprit
2. No spark
specifically for the 4g63 engine which is distributor less... the things you need to check are coil pack, transistor, CAS (cam angle sensor), Powe relay from ignition to ECU, ECU.
But for tammy, i have checked all of it already but everything is working! I was at my wits end when a friend unknowingly pulled the wiring harness! and the symptom displayed... we had the "AHA" moment.. We just found what the culprit is, its the harness the wiring pulled off! so right now tammy's harness is currently pulled out and have all the connection soldered.. whew!
Thanks to phat_tricks and Chester for towing my car and helping me out solve the freaking prob!
i'll post some pics later
