Guys:
"Or f'd on race day!"
I am around but doing other things.
I used to like my truck, but after dropping nearly $2G's in work recently on it & me supplying the parts in that cost & getting you know whatted over by a pr mechanic.
In that parts list I had a rebuilt ECM as this highly recommended mechanic told me he was getting F, G & H fault codes on his shop scope.
I yaint happy. I'm thru crying the blues.
Yes my idle is out of whack. It does idle about 300 RPM's whilst in gear sitting at a light or stop sign. I replaced the MAF sensor & the idle is still euchred. I have an OBD reader & after running the KOER test, it specifically references the IAC needing attention.I had a similar problem with a 5.0 motor explorer that was a vacuum hose that had worked itself loose. I am unable to find any hoses that may be loose causing a vacuum leak. I have a gut feeling, the mechanic did something to guarantee repairs for him, and a make work project. It feels like it wants to stall, as I am braking, and it hesitates when I hit the gas. It is not a smooth acceleration any more. It is a 4.6 l motor.
I even tried to discharge the diodes after checking out my symptoms on line.
To see if that would do a hard reset, bit got the big goose egg, no improvement. So any back yard DIYer's wanna offer any me another avenue to try. Pls and thanks.
