Hello. I have a question and I was thinking perhaps one of you small block cobra runners (using EFI), might be able to help me with.
It is not cobra related, but without searching around on the net and looking, I don't really know where else to look.
I got a 93 Ranger with a 3.0l V-6 fuel injected engine.
It has a particular problem, that I think is not engine specific, but "system specific".
When its cold, in the morning (worst in winter), It starts fine. But when I put it in drive and go to accelerate, it feels like im pulling tens of thousands of pounds on a trailor. Absolutely no acceleration. Gearing, is irrelevant. As the truck slowly starts accelerating, the engine then starts to "pulse". Pull (accelerate) decent, then falls on its face (no acceleration), then pull, the fall, then pull, then fall... As speed picks up, the pulsing gets closer together. It does it worst in winter, but also on hot summer days. (though its less noticable). After driving about a 1/4-1/2 a mile, the problem is gone. I assume the engine has warmed up enough that the problem has temporarily went away.
Anyone have any ideas? I ran some fuel injection cleaner through the engine, but I realize this is not the same as a professional fuel injection cleaning job. Results: no change.
Im not sure if I've tried it, but I think i might get some air intake cleaner, and work over that valve. (I forget the name of it) on the plenum.
I also believe it was doing this problem when I took it to the mechanic to have the mass air flow sensor changed. It came back with no scan code errors.
You can email me, if you have an idea. I'll try to check back as soon as I can.
Thanks in advance.
(btw, while its not cobra specific, this same problem might inflict someone with a fuel injected cobra.. .so, I guess it is sort of on topic).
