Hello everyone,
I have a 1995 Ford Ranger XL 2.3 manual transmission, it has a hard time taking off from a stop, I have to rev it high and drag the clutch a bit to make it move, after it starts moving it pulls fine, is like trying to make another car take off on second gear.
I already fixed the throttle cable slack these are known to develop, the throttle position sensor is new, so are the coils, sparkplugs and cables; the injectors where cleaned, oxygen sensors are new, so is the catalytic converter, EGR valve is new as well, exhaust pressure sensor is new as well as the other exhaust gas recirculation related stuff, MAF sensor was cleaned, air filter is in good condition, gas pump and filter are new, so is the clutch system, it is not showing any codes.
Compression is at the lowest mentioned on the manufacturer's manual, 91psi average, and the gearbox is whining a bit, but goes through gears smoothly.
I bought this car used for peanuts, I put it back together doing all that stuff, it has this issue since I bought it.
Hello,
90PSI is extremely low compression ratio,
It sounds like the engine is just tired,
Try taking off with the AC off and see if it helps, If it does you have a compression issue.
All the Best.

Thanks for the answer, engine rebuild and gearbox overhaul are next. Since the maintenance manual mentions 90psi as the lowest, I was hoping that I could squeeze a few more miles out of it, looks like that won't happen.
Cheers.
