1993 ford RANGER 2.3l will idle fine but wont rev up. falls flat. have checked spark on all plugs, has new ignition module, checked timing, has exhaust flow out tail pipe, have cleaned mas airflow sensor, and checked fuel pressure. any ideas???? the last time I read the codes it had a 151? not sure what it is and I think was 452 vehicle speed sensor?
Does it have an accelerator cable ? if not , it may have an electronic

First confirm it is either gas or eastter. Wayer/condedste collects at the tail oip as a byproduct of the caralyctic converter on cold rngine It normally occurs on firts start of a cokd enginw. the ebgine idles low because it is col, but should reyutn to normsl after warm uo.. If for sure iys gasolinem and the engine runs eiygh, then angihector is bad, good luck. I hope this helped yyou

With out a check engine code there could be few things that can do this, clean the mass air flow sensor, check your engine air cleaner and then if this doesn't help, have someone start the car while you watch the throttle linkages, after it warms up watch which linkage moves when the engine speed drops this will be connected to the problem sensor / auto choke. Try unplugging it to see if it helps before you go out and buy a new one.
I hope this helps

Since you have replaced all those parts already, I would suggest checking out the egr valve. Also I was wondering how the coilpacks or distributor are acting? Is the truck firing on all cylinders? Very possible you have leaky injector also.

Hello Charles...I don't know what engine package you have in your ranger the 3.0 or 4.0 litre, but regardless, a diagnostic scan needs to be performed to determine the cause of the problems. Sounds like the Electronic Engine Control (EEC-IV) has stored hard codes. A self test can be performed where Diagnostic Trouble Codes (DTCs) are transmitted on the Self Test Output (STO) wire located on the vehicle self test connector. The codes are in the form of timed pulses, and are read by the technician on a scan tool or the CHECK ENGINE light. With the information recieved the proper repairs needed to correct the problem can be determined, other wise you are just guessing.
Good Luck...i hope this helps and will fixya up.
