1995 ES300 headaches
OK, so here is the situation. I'm working on a 1995 ES300 that wants to die out off idle. If you ease into the throttle it will usually pick up some, but the exhaust manifolds start glowing and it's still very under-powered, to the point of being un-drivable.
The CEL is on, but I can not pull any codes from it. I have tried jumping the diag terminals at the port under the hood, but the CEL doesn't flash. I tried the one under the dash, but there is no terminal in the Te1 slot, and I've tried hooking a generic scanner to the obd2 port by the fuse box, but it will not communicate with the scanner.
I replaced the cat, since the pipes/manifolds glowing usually indicates a clogged cat, but the difference, if any at all, is very minimal. I have also checked fuel pressure (35psi at idle, picks up to 40-45 when you press the throttle) and ruled out any vacuum leaks. Pulling and plugging the vacuum line to the fuel pressure regulator results in a consistent 45psi, but still no change in how this thing runs.
I have not checked the timing yet, but seeing as the problem started off as an intermittent problem, I can't see it being in the timing. If it had jumped, it would always be off.
I am thinking either MAF or ECM at this point, but any advise would be greatly appreciated.
