Hello,
I've not been on this forum in years. I sold my Scion a while ago and have been through a few cars since.

I donated my knowlege while I was here so I hope you guys can help me out now.

I'm trying to help my brother-in-law out.

When he go to a stop his car idles rough and stopped running once.

It is a 2005 with 89,000 miles.
I was going to give it a tune up while we were at it.
I'm going to change plugs, fuel filter, run some injector cleaner in it.

My guess is the trottle body or the MAF is causing the ideling issues. No CEL lights at all.

Any suggestions for the tune up or how to fix his problem?

Thanks in advance.

 

Nevermind a litte shot of CRC MAF cleaner and the car is right as rain.
