Over the past months, I have been doubling back on all the systems. When a vehicle goes from sitting 20 years, to cruising the Dallas Tollway at 80MPH... junk will be kicked up.
The big focus has been fuel delivery. Fuel filter, injectors, seals, grommets, FPR, Damper, etc.
I pulled the injectors and had them sent out to be cleaned by InjectorRX. Injector 3 was the worst at 17% plugged. Once the fresh injectors went in, I also adjusted TPS and Idle control sensors to FSM spec. This thing purrs now. Here are the results:
New Injectors and FPR:
Fresh OEM fuel filter went in. Here is old dirty filter:
