Help Diag my Girlfriends car
1994 1.8
Megasquirt gt2554 Toyota COP 550cc's Ran fine for the 1st year or so Lately, Her car is acting weird, While normal driving, hwy or city, hot or cold days, after a while, the car goes develops a misfire out of now where. If we turn it off and let it sit for a while, It will start up and drive normal, and after a bit, it'll repeat the process. We've managed to limp it home, but its still weird. I just got her new injectors and we're going to get the car re-tuned but need to solve this before getting on the dyno. Just did a quick search and found it may be the CAS sensor overheating? I don't have a laptop with megatune or tuner studio anymore unforuntately |
You need to get a laptop with tuner studios.
I would switch out to new spark plugs and lower the gap on them a bit to see if that helps. CAS usually don't over heat and go bad, usually it is the cam sensors on nb's that have that issue. |
Swap in a known good set of coils and see if it goes away.

Failed to mention she has a COP conversion. I do have a new set of coils to swap in from my mr2s spyder. (same as the corolla) and i'll try that. Didn't know if the Cam issue was isolated to NB vs all 1.8

Spark plug wires
Edit: missed COPs post ~ignore~ Check/replace coils |
Maybe because it's been on my mind recently - fuel pump?
