I've been rebuilding a mazda for some time now. everything is great except the engine. At an idle or when its cold it runs great. Then from 1000 to 3000 rpms, it dogs bad. As soon as it hits 3000 it launches with full power. It is a 94. There is no cat or exhast. I have replaced the MAF sensor and checked the TP and ECT sensors. Any suggestions? maybe inlet air temp or crankcase positioning sensor?
