At the local parts store this morning and saw cans of CRC MAF Sensor cleaner and Throttle Body Injector Cleaner so I added them to the purchase, and figured I do some quick PM when I got home. Cleaning is easy and very straightforward. Everything came apart, cleaned up and back together in matter of minutes.

Went to crank it up and the old 97 1FZ-FE purred. Except the CEL came on. Oh s***.

Spent 30-40 mins running error codes and googling issues. Did I do something wrong? Too much cleaner??


No. Remember to reconnect the damn MAF wiring harness!


Alll good 2 hours later!
