Frustrated

[livingez_123]

Things get old, and parts wear out and at sometime you end up replacing all kinds of stuff. And it never fails when one thing goes it's all downhill from there. Make a list of things that need to be replaced and put a priority on it and do a little every month.

New Pcv valve.

Clean throttle body with toothbrush/carb cleaner. An iac valve could be cleaned.

New plugs buy good one! Wires MSD are only $45.00, clean your coil packs and or replace. Sea foam it in the tank and through the brake booster, clean Throttle body butterfly plate. And whole throttle body easy., clean MAF sensor. Check fuses and relays on electoral issues . You can do a basic alainmen in your driveway or pay to get it done. Run a tank of premium fuel although Colorado doesn't have as hi a octane as here due to tree hungers!


Note: do the see foam before you do the tune up so new plugs go in afterwards!

I believe on these engines the wires come with the coil packs installed in them? At least that is how it is in my GMC Yukon Xl Denali?
