Idle surge. What idle surge?
Took the throttle body to Ethan’s house and practically did a rebuild. Upgraded seals and ISC motor (from a VR4 TB) and sealed off the cold idle port on the throttle body. Thanks to Ethan and his Dad for showing me the tricks of DSM. Hopefully this makes megan stop surging and it will save my tools some pain because ive been throwing them too much.
We began to use the timing light when we realized cylinder #1 was not sparking correctly. After switching the spark plugs from cylinder 1 to 4 and 4 to 1, correct sparking resumed. Unfortunately, the idle surge is still present.
Trying to resolve the idle surge issue with Ricardo.
Okay, so the car starts, but dies shortly afterwards. The idle will rev, and as soon as that happens, then the car dies. I spoke to Ed and he told me to check the capacitors on the ECU. That’s what I’m going to do.
Here are the posts and forums I am going to use:
