Hi,

My '89 Civic has been sputtering lately, especially at low RPM and it gets worse after it's been driven for a while and the engine is warm. It is not bad when I first start it up and drive it but after 20 minutes or so, it sputters badly when I'm at a stoplight.

Can anyone please help?

Thank you.

Replace the Ignition Control Module (ICM) and coil:
