1988 Ranger 2.9 with auto trans.
I got this as a non-running truck but it fired right up after I changed the ECM relay. It ran fairly good on 7 year old gas. Just had a small hesitation when you'd hit the throttle. Fast forward a few month and one day it just started missing terribly and the hesitation is now pretty bad.
Things I've done:
Air filter
Fuel filter
plugs, wires, dist cap and rotor
Looked for vac leaks and didn't find any.
I kept messing with and driving it short distances. For the most part it's stopped missing but will still stumble pretty bad. While it's stumbling, if you let off the throttle it instantly clears up and runs on all 6. Eventually if you just hold the throttle it will snap out of it and take off like normal. This mostly goes away after it gets warm. There is no CEL.
What should I check? Trying to avoid the parts cannon. The items I've already replaced where long overdue so I don't feel bad there.
