Electronic spark control module

Hi, Spark is controlled by the computer. Where and when(timing). You can not change that. Each cylinder has 1 coil and spark plug. That module is built in to the computer. There are sensors around the engine that send info to the computer. Air, spark, timing, and fuel. When these things work properly the engine will run.

1990 corvette idles rough sometimes. Sometimes it runs great when I start it up. then other times it wants to stall and I have to give it gas for a while but it still idles rough. It's either one way or...

Sounds like a clogged fuel injector.
Or worse one starting to go bad.
The problem with your car is the computer system readout is analog.
older models have a OBD-1 system and it makes finding the location of a bad injector a lot harder to find.
You could try a after market fuel additive called "sea-foam"
Most Wall-marts carry this product.
Give it a shot,I've done so myself on a VW VR-6 and talk about finicky fuel injectors!.
Worked really well for me,hope it does the same for you.

1. Monitor the 5v reference, Gray wire to the Throttle Position Sensor (TPS) with a Digital Volt Ohm Meter (DVOM) set to the MIN/MAX setting.

2. Monitor the TPS signal circuit, Blue wire with a DVOM. Voltage should range smoothly from approximately 0.44 to 5.0 volts as the throttle is opened.

3. Tap test the Electronic Control Module (ECM) and see if the codes come back or if the engine reacts.

possible causes wiring or Powertrain Control Module (PCM)

I just read the diagnostic codes on my 1990 corvette. I have two codes showing on the digital speedometer A Module 1 (CCM) Code C12 A Module 4 (ECM) Code H34 What do they mean? Thanks for your help!

Code 34 has to do with your MAP sensor I believe from what I am reading. I don't know a lot about corvettes but it says MAP sensor voltage low. The C12 code I see is a normal code set dealing with no reference pulses being received by control module. In other words with the engine not running. It has to do with No RPM reference pulse.

It sounds as if the Ignition Control Module has failed. Remove the easiest spark plug you can reach. Reattach the plug wire and clamp the plug down to the valve cover or something that will make a good ground or electrical path. Have someone crank the engine while you watch to see if there is a spark across the electrodes. DON'T HOLD THE PLUG WHILE YOU DO THIS, IT WILL KNOCK YOU ON YOUR ****! If there is no spark chances are the ICM is bad. It's located on the left front behind the Pwr Steer Resevoir on the engine block. You might be able to remove it, 2 small screws, and have it checked out a a parts store. If you don't have any luck with this post your problem on There are many there that will help.
