Hi
86 Ranger 2.9Lt. I brought it home on a trailer from junkyard where it sat for 6 years, I was told it had unspecified engine trouble.
Since Im unfamiliar with fuel injected engines thot I would tell you what engine runs like. I just did oil change it ran the same b4 & after.
Hot or cold it starts fine.
When its stone cold, start it up and it runs like a new one, as it starts to warm RPM slows so I havta go turn up idle screw to keep it at 1000RPM, warms up a bit more RPM slows again and I havta urn up idle screw some more, and so on and so forth. When it gets to operating temp it sputters like its missing always in the same manner, give it some throttle and idle at higher RPM and it sputters exactly the same way no matter what RPM you run it at. When you step on it sounds like it runs fine till you stabilize it at a higher RPM.
I dont have a gas tank rite now so I stuck fuel line and return line in a 2 gallon jerry can and I overdosed gas with injector cleaner I ran it for about 30 minutes in total. I put a low pressure pump on the fuel line. I hear the high pressure pump run so I guess its ok. Fuel supply looks fine, when I push down on that valve stem looking thing where your spozeta check fuel pressure gas shoots out so I assume fuel pressure is good.
Assuming that all other things are ok, Is there something about fuel injection thats causing the problem??
