CEL is on.
Car runs retarded rich on idle
OBC reads 9.5mpg, and I've been driving very conservatively. I know the OBC isn't accurate at all, but in comparison I was doing 19mpg city according to OBC before.
Idle is a little rough.
Stumble on WOT
Timing is correct
When the engine is completely cold in the morning, I can turn it on and it will idle normally, at like 1500rpm since it's cold. It sounds great, then in about 2 minutes or so the RPM's drop completely and the car will idle at around 200rpm and wants to die. I have to keep the car revving until it gets warm, then it could hold idle, but rough.
Spark plug color is normal
No OBVIOUS vaccum leaks, I sprayed down every where where they would be a leak and nothing, except on the ICV port where I fixed that.
things i've tried diagnosing:
I adjusted the TPS so it "clicks," nothing.
I removed the dipstick while it was idling, and the idle stayed the same.
I removed the oil cap while idling and the idle stayed the same.
I rewired the C191 while doing my head, so I thought I might have screwed something up. I know the injectors are wired right since the wires are different from the temp sensors, but when I remove the blue sensor connection on the thermostat housing (coolant temp sender?) nothing happens. the car stays the same, the temp reads the same.
additionally, when I unplug the O2 sensor, the car still idles and feels the same and everything.
When I'm going on lets say, 3rd gear, at a relatively low cruising rpm, there will be SUPER SUPER slight moderate hesitations that would only be noticeable to me but no one else.
Help r3v!
