KJ Wrench day.
Poor KJ had a bad day yesterday starting cold.
Even though it has a new TPS, 6 new coil packs, it had tons of cranking power, yet hesitated to start, rpm's dropped, and stalled twice.
Hmmm.. cold pintle not moving properly to allow air in=eek! Tired of cleaning it anyways.
So I called yesterday, & ordered a new IAC. Picked up the new IAC at 7:45 AM today.
Dealer wanted ridiculous $ for their IAC..went with a..

Hopefully my cold start issues are gone now...will see...
Took me about 1.5 hours to install the new updated PCV system Link:

SO that's all good now...
Bad news is.. I still have misfires/slight engine shake, just slightly above idle appearing on Snap On Scanner! 1-2 counts, random cyl 1,2 5 etc. eek!
No misfires at dead idle park, or drive, or other rpm range it appear.
Carb cleaner used around intake no drop rpm, no codes, no clues other than a solid guess of injectors/dirty valves..
So now that the new PCV system installed, I am going to try to find a local shop with the Professional induction, hook up to the rail cleaning.
Then take it for a long highway drive 300 miles plus, and see if that changes anything.
Tell me I do not have to remove the intake, to peek at carbon....
then have to install 6 new 4 spray injector etc...etc...
