Rich fuel at idle

[RichRab]

Ongoing problem with rough rich idle up to about 1000 rpm. Checked everything and dealer said he thinks it is a bad injector. An injector cleaning service said most of the times injectors can be tested and and cleaned. No charge if it is not repairable and they do not sell injectors. Any opinions on which way to go? Thank you. RR

Get it tested and cleaned

Before you get it tested try to find another injector just in case it's a damaged injector how much is the cost for a testing and cleaning

20 dollars each free return shipping over 4 injectors and no charge if not repairable but marina suggested a local guy and. Said about $25 each to test and repair if repairable.

Update...took injectors out and tested. He said number 4 was dripping. He cleaned them and I put them in. On trailer it seems better. This was my first time removing fuel injectors and it was not hard. $25 each for service.

Seems to run better but still rich. Going to try another mechanic. Changed map sensor in addition to iac and tps. No vacuum leaks.
