96 Ranger Stalls and Misses when Accelerating and Low RPM's

acleme1 · Oct 2, 2008

Hello all. I have a 1996 Ford Ranger STX 4x4 with the 3.0 V6 - Standard Transmission. Engine has been missing and stalling when accelerating and at low RPM's. Check engine light came on a few weeks ago, and had to replace ABS Sensor and a pressure sensor in the fuel line (can't remember the exact name of the sensor at the moment).

That didn't help anything. Engine is still missing and stalling at low RPM's and when accelerating after releasing the clutch. engine runs like a champ at high RPM's. Runs like crap at the lower RPM's. Engine idles fine.

I haven't replaced plugs and wires yet, but plan to. Can anyone out there give me some suggestions/ideas on where to start looking or problems? Any help would be greatly appreciated.

any black smoke from the tailpipe? you might have someone watch the pipe while you drive away since its hard to see from the cab.

are you loosing coolant or gaining oil? does the oil smell like gas?

One very important (and always overlooked and easy to spot) part of your fuel system is the throtle body. Even though the symptoms you describe can be related to thousand things... Inspect the throtle body. Dirt and sludge have a tendency to clug this very important part of your motor and the symptoms are very (if not the same) similar to what you describe. To inspect this part You have to remove the air intake hose. Once You see the throtle body turn the accelerator all the way with your hand. If the back of the throtle is black or there is any sludge buid up on the edge of the throtle body (around where the throtle seats at full closed position) you need to have it cleaned. If You don't have the skills to do it have it done by a Pro. Cleaning the throtle body the rite way requires it to be removed from the intake manifold. Cleaning it on the intake can create a dangerous situation with the cleaning chemicals. Always think safe.
