My vehicle is a 95 Mazda
Protege, 1.5L engine, auto transmission. My problem is that the car runs perfect at
idle, but soon as i try to accelerate, even in park, it just bogs down, and
no power. Even if I put it in drive, it will not even move itself, and just stall. Spark is good, plugs are new Densos, compression, fuel pressure, (38 psi at idle) and spark plug gap
is in spec. The fuel pressure rises when I snap the throttle. All the
filters are new, and there are no vacuum leaks. I have even checked the
voltage values of the TPS, MAF, IAT, MAP, closed throttle position sensors and
load/no load distinction signal...and are all good at the PCM. The only thing that helps is when I spray air intake cleaner in the intake tube through the port where pcv valve enters. I give a quick spray and snap the throttle open, it revvs up properly. I don't know if anyone has heard of this problem before. As the proud owner of a 87 Mazda 323 which has been basically trouble free for years, i bought a Protege that needs a little love and care. CAN YOU PLEASE HELP? Thank you,
Brian
