I have 1986 Ranger 2.9L 4x4 manual. Recently after the engine has been running for a little bit it slowly progress's to barely running at all. When its cold I can do what ever I want, it runs really strong. Accelerates normal. But when warm it struggles to get above certain rpm's until barely running at all. Then after cooling completely down it runs really good for a certain amount of time. I'm stuck on what it could be and I don't really want to put the money into a mechanic fixing it.
A month ago it had running problems which turned out to be a faulty fuel pressure regulator. It was pushing 120psi. I've had that fixed now and now this is happening. The dealership also mentioned my egr needed a looking at, but could be giving false numbers because of the fuel pressure regulator. So I just had the regulator replaced. It ran good for a while until now.
I have within a year replaced the spark plugs, wires, cap and rotor, air filter.
I change the oil regularly.
I have noticed that the temp gauge never gets up to regular operating temperatures recently. I've also been getting lower than usual mpg's, i get near 14 right now and I used to be at 22-23.
And one of my recent drives when it acted up, for some reason I decided to look under the truck and my catalytic converter was glowing red hot. So that is working overtime, correct? I'm running extra rich? Might explain my recent mpg's.
I've leaning towards egr or a temperature sensor. Or maybe something with ignition because it has issues getting to higher rpm's when warm. Or a ground somewhere. Or maybe a cat conv that melted down. Or the fuel pressure regulator was misdiagnosed or installed wrong.
Any kind of incite would help a lot. Thank you.
