ok, 1994 mazda mpv, serious lack of power issue.?
driving home from the airport, it started to act up. lacked any power, had it towed home and let it cool off a bit. trans is only a half a quart low, but that is not really the issue. i can hold the throttle open and the engine just bogs. does any one have any info on this beast. i need to know the compression pressure for one and any other info that you might have that might keep me from just blowing it up.
it is an obd1 system but i dont have a scanner with me. i will be running some tests in the morning such as compression and tps sweep. i do not smell fuel what so ever so i really dont see that is a possibility. the fuel filter has not been changed in quite some time, but it does not sound like a fuel starvation. plugs and the rest of the ignition system of that nature was changed about 15,000 miles ago. i am not elimination that but it does not sound like that.
ran it again this morning after checking a few things. it will only rev to about 4000 rpm. the cat is my next idea. if i can not unbolt it and get higher rmps out of it ill be pulling the o2 sensor out for similar results.
pulled the o2 sensor out and it ran just the same. it will not accelerate very well at all.
failure, folks i found the information that i was looking for elsewhere. cylinder pressure should reach between 145 and 165 psi.
