92LRC | Bad Opti? Part 2 | ||
Guru Newb
|
I posted a couple of weeks ago that I thought my Opti was going First Post
I cleaned up and checked all the connections but I'm still stalling after a bit. I started hearing popping sounds coming from the exhaust. I had heard them before but not as often Listen Here Could this be part of the problem? This is what happens when the stalling starts after the car has warmed up. NOte that the jumps in RPMS are happening by themselves I'm not on the accel. Stall 1 Stall 2 Not throwing any codes, none that are holding anyway. And it never fails to start, it just won't stay lit. I don't want to rush right out and change the Opti and throw $ at the problem. Thanks in advance for any input. Serge |

Ah... start with the coil and ignition control module.
They mount together on the right front cylinder head. Inspect the coil wire to the opti and the harness to the ICM. Also, inspect the harness to the opti from the ECM. This is a 4 wire bundle that runs past the injectors and down into the water pump. If you are not getting a code, you could have some of the worst possible carbon tracing... EVER. And that would require a new opti at this point. |

Sudden unaccountable jumps in RPMs would indicate the ECM, unless it is a Toyota, in which case check the floormats.

RPM jumps are from carbon tracing, too. But I can't prove it... photobucket hates me.

would a dying opti not do that as well? The thought of a bad ECM makes me want it to be the Opti. Aren't ECM's for 92's pretty much impossible to find? |
