yes it's a direct bolt on replacement. i cannot remember if all SSEi's had it, or not. hopefully someone will chime in with that info, or at least the RPO code to check on the parts car to verify.

my SSE was the same way, overall its kindanormal. These cars seem to have a underpowered, and chinsy electric system. I Changed to a 140amp alt from a 92+ SSEi and a larger battery, seemed to help quite a bit. i also replaced my battery cables as the ends werent corroded, but once i peeled back the ...

the only reason you should have to go with the more expensive one is if you have the RPO code on your spare tire cover that says GX3. which I'm going to say you don't, because I'm 99% sure it wasn't available in 89. only 90/91

Don, big diff on the special mount for the GX3... my shop tried using a regular one for $75, and my trans tore it up in less than 5k miles. replaced it with the special mount, and was good for the next 20k i had the car. (im sure its still going)

the issue is in the cluster itself, very common on the 88-91 gen. the short is in the plastic ribbon/board that runs accross the back of the cluster

Okay, i'll give it a try

is the ground for the icm box used thru the three screw posts used to attach it to the mounting bracket?

this is still a ongoing problem. still no spark on cyl 3 or 6. i've done my best to check the wiring from the CPS to the ICM and everything seems okay. i've even wiggled the wiring while the car was running with no change. every once and awhile i will get a slight spark real quick on 6, then it ...

had the crank sensor replaced and aligned using the original GM tool. car ran super good for two days. now running worse than before.

car is very hard to start, with extended cranking time, sometimes no start at all.

found out the car is running on only 4 cylinders there is no spark to the top ...

figured out the TACH problem, the plug on the ICM wasnt 100% tight. but the car is still running like poop. i've also noticed i get a misfire in park at 1200 rpm.

UPDATE: i noticed something i hadnt before, the TACH is jumping around like crazy in park idling and when driivng. it isnt anywhere near what the engine is actually doing.

i havent replaced that, anyone know if this is something that could cause it?

anyone? *bump*

215k on my 90

i replaced the plugs and wires prior to the harmonic balancer. i replaced the ICM after.

its really hard to say how the car was running prior to the harmonic balancer replacement. the balancer was so bad the car would barely stay running. (it was extremely loud) also the car sat for 9 months after ...

well got a new fuel tank, new lines, and new cat and muffler. still has a bad hessitation from a stop, and surging/misfiring above 45. i only get the misfire/surging at low RPM's once the TCC kicks in. I'm at a loss....

its a GM Brand one.

could a leak in the exhaust be causes this? there is a hole in the muffler causing a louder'ish exhaust

i swapped out the IAC, MAF and TPS with ones from a known good running car. so its not any of those things

computer shows no codes at all.

i cleaned the TB yesterday

i put new vacuum lines on last year, and i checked them all over again. all are fine.

the coils and ICM are all new. i swapped it out with another one(older magnavox style) and still ran the same way

car spits and sputters only under 1500 rpms.

will barely stay running at idle when coming to a ...

also, it is idling around 1000 to 1200 in park, idles at 1000 in drive. (according to the tach) it was idling much lower prior to the HB replacement.
