Hi:
I have a stubborn problem with acceleration on my 1990 4x4 Toyota truck with 22RE engine.
It has poor acceleration in almost any gear UNTIL I either floor the accelerator OR the RPM climbs high enough (perhaps over 3000 rpm?). It seems almost a like a vacuum advance problem except that this engine doesn't have such a system.
It idles fine and it accelerates like a bat out of hell once I floor the accelerator or the rpm gets high enough. I've checked the plugs, air gap in the distributor. Timing is right on 5 degrees with the appropriate contacts shorted out.
Any ideas that I could look at?
Dave
