i have been having problems today getting it to rev past 3000 rpm and when it gets close to that it feels like its hitting a wall and it backfires.

whats the best way about fixing this problem? im trying to sell the car and obviously i cant sell it without it running properly.

my scan tool thing that i have says it is the electronic spark control module or sensor. and when i called autozone/schucks/baxters they say their computers dont show any listings for that part...i need to get this straightened out asap.

any suggestions, or has anyone had this problem before?

Isn't it the icm in the dizzy you replace or this one? I've got an extra one if you wanna give it a shot, I was gettin 43 when I was in az and I just swapped it out, not a thing since. Its out of an 88 firebird I never tested it but I've just kinda collected parts over the years.

Also I've heard if you're using a high octane gas it will throw it as well, my dad wanted to drive my car when I was in ft jackson so he put 91 octane in with more octane booster to "freshen it up" too bad it causes predetonation lol

Hope you get it fixed

ya thats what the part store guys thought i was talking about. i have never replaced that but wasnt sure on buying it because i dont want to just guess on what i need to replace...how would i know if the actual knock sensor is bad or not?

[rjmcgee]

[jakemk8706]

well im definitely not running high octane gas...

[BluFbdy]

That was just my experience with it, car ran pretty bad, kept throwing codes it was fine after I filled up with 87, anyway if you wanna give that a shot I could dig it out for you, its what like a 3 min deal to replace?

As far as the knock sensor goes I remember someone saying to unplug it and try to run it but that seems too simple maybe someone can chime in with a better answer

[blue89]

Sounds like the ignition control module. Did you put a boat ICM in there?

Oh no I mean good luck with finding parts guys that know remotely anything. Just like any job nowadays, they're getting hideously diluted with people that don't really care.

And yes, I agree. It should be fairly easy.

[jakemk8706]

so if i replace the icm and it doesnt fix my problem, i should then look at replacing the knock sensor?

[RSFreak]

[jakemk8706]

Well I had the icm tested at autozone and it came out good. So what now? Replace the knock sensor?

[chevymad]

Anybody wanna explain why having a module tested is about worthless?

[aaron_sK]

I was under the impression that, like bench testing a coil, it has something to do with the ambient temperature of an Autozone store, versus that of the interior of a distributor cap.

Of course that may just be the beer thinking for me.

[chevymad]

Ya.. temp has a big thing to do with it. Also I'd say duration of the test.

[jakemk8706]

Hey chevymad, I appreciate you making feel like an idiot, but I'm trying to find solutions to my problem. I thought this was a website dedicated to that. If I'm wrong please correct me.

[aaron_sK]

Hey man, we're all trying to help you out here. If we're coming across as smartasses... that would probably be because we are smartasses.

Buy a new module; a good one, not a Chinesium crap.

No kidding, don't buy a brown car.
