I've been having this issue for the last 2 weeks, I've been looking through multiple forums trying to pin point the cause of my issue.
Issue- While driving the vehicle the car will stall for a split second, normally dropping the rpm's by a 1k then goes back to normal. The CEL does come on and goes off after roughly 5 seconds. This happens no matter what throttle % the car is at or rpm however it won't do it while it's idling. Sometimes it happens repeatedly every 3-5 seconds or takes minutes between to do the stall.
At first you could hear a click behind the radio, so after much research I pulled the ecu and found the board to have corrosion/ leaking at the caps and on the knock board (or at least the ecmlink calls the board this). Instead of replacing the caps I ended up picking up a different ecu (92 gsx mt ecu) that appears to be in excellent condition. Went ahead and had the caps replaced and my dsmlink v3 chip and socket installed.
Installed the new ecu and same thing, car still bucks at random rpms and throttle %. Still throws the CEL for a couple seconds and the car returns to driving normal till it happens again.
Before anyone ask, I tried to datalog the issue and reliezed every time it does this the log stops recording. Link says it's still connected but I lose datalogging capabilities when the car bucks.
Sorry for the long winded post. I don't want to throw money at the issue. I'm thinking about replacing the mpi ( correct term?) relay next to the issue but would this be causing my issue or should I be looking at something else?
