We just replaced the Ignition Control Module in our 99 Chevy Suburban yesterday and from all appearances it seemed to run fine all day today. Then later this evening I was out running errands and ran into a store for 15 minutes came out and it struggled to start as it had before we changed the ICM. Took about 3 or 4 times to start. It eventually started except now the Check Engine light is now on (this wasn't on before). I'm assuming because of maybe a faulty knock sensor now because of the hesitation in starting of the engine? Could we now have a problem with the Knock Sensor and or the Ignition Coil?
have the same problem?
