Hello everyone

Does anyone have a cold start idle problem?

A few minutes later the idle will be okay or the second start is okay too. Above, I feel losing the cold start program.

Please help!!

I would be checking the maf or idle control valve. Best to get a scan done and check what readings your getting.

Thank you

Thank you for your reply

So I spend a week on the test. Every time the test I need to wait for a car cold down. Finally, the problem solved today!

I check the MAF, ECU, Test vacuum leak (use the Smoke machine)... The problem is the solenoid valve. The problem not easy to find it, because it isn't obvious in the Smoke machine test.

Thank you, everyone. I thought I can not find it, until yesterday I ask on here.

I hope this problem can help need friends.

Thank
