1992 Mazda b2300 4 cyl 5-spd Two Wheel Drive Manual There is no shudder or perceptible slipping of the clutch when I accelerate. Acceleration is very slow. I have to rev the engine to 3500-4000 RPM's to eventually get up to speed.

if it is eng. power loss, check air filter, fuel filter, fuel pressuer and volume. could be cat. converter plugged. will it red line in nuetral?

Doesn't seem to be loss of engine power. I can rev as high as I want in neutral. I have to rev to 3500-4000 RPM's in gear to get it to accelerate.

will it coast ok? do you smell a any oders when starting off form a stop, and do you have the problem taking off from a dead stop?

Coasts fine. No oil or transmission fluid oders. From a dead stop, goes into gear ok, no shudder or slipping. Have to rev engine to 4000+ RPM's to gain momentum, same through all gears, takes a while to get up to speed, especially uphill against a head wind ;)

i would have your clutch inspected - don't think its got much contact.

ya, have a repair shop take a look at it.

yeah, that's the conclusion I came to. Decided I did not want to get it fixed. Just got back from buying a new one. Got a great deal, $3,500.00 rebate. Gonna put an Amsoil dual oil filter system on it and use aircraft engine oil. Gonna drive it for the next twenty years! Thanks for the comments!
