Some help with my car
its a 90 lesabre ln3
okay, My ICM died under the coils, I replaced the icm, it runs, but I have some problems and here is wat I have done
new coils, ecm and belding plug wires, new ngk tr-55'*
took throttle body off, cleaned the TB and all sensors accordingly to the guides on the site,
cleaned air filter and oiled.
replaced my battery connectors as they were old and stripped threads.
now. when it is cold, the car seems to have no go. warm it goes decently.
this morning (first time this ever happened) when I started the car up, the Tach needle was going NUTS, i pushed the brake and it went normal, let go it went NUTS. I then opened the door, the tach went normal, closed the door, it went nuts again (but the car was not misidleing) after putting the car in gear it went normal.
Also I am still getting a studder when cold sometimes.
once warmed up it does not misfire and has power and goes fine.
everything is clean no SES light at ALL.
I am wondering could it be the computer or ground bus? because I get no SES light at all. any help appreciated. thanks!
