#2685 of 2995 1995 Ford Ranger faild Fuel Evap Test
May 09, 2008 (5:05 pm)
I have a 1995 ford ranger 4 cyl. 2.30 eng. I tried to have it smogged today and it failed the fuel evap test. I understand this has to do with a leak in the fuel system from the tank to the fuel pump. Leaking fumes. If some one can let me know a good place to start. should I replace the fuel fill hose or ck the vac. hose from the tank to the fuel pump? would be happy with any help thanx
#2686 of 2995 Strange noise

I have a 92 ford ranger 4x4 2.3L 5 spd, i hear a whining noise at certain speeds and i believe it has something to do with the front wheels, the hub lockouts are not working properly, could this cause the noise?
#2687 of 2995 Consistent Misfire
Jun 09, 2008 (10:14 am)
98 Ranger XLT 4.0 2X4, 198,000 miles. The engine misfires consistently at idle and under load. On the freeway, it surges back and forth. There is no colored smoke, or indication of mechanical noises or problems, just bad misfire as if from an ignition system problem. It even still continues to get respectable fuel economy, despite the loss in power.
I had similar symtoms about 6 months ago (the engine had been misfiring for a while when I finally took care of it; it's my friend's ride), replaced the plugs with Autolite "double platinum" and new Motorcraft O.E. ignition wires. After replacing the plugs and wires and reconnecting the battery (clearing the CEL), it ran great for a few months, without any hint of misfiring. Good as new, I thought...
Recently, the misfiring started again as bad (or worse) than ever. I've checked the wires to make sure all was well-seated.
I have codes from the OBDII reader at Auto Zone:
The codes seem to tell a story of "something's wrong in the EFI/Fuel System, but I don't know what."
Before I start on an endless quest of replacing every component in the system starting with O2 sensors, does anyone have experience with these same problems, and the likely fixes?
This truck looks like crap but has been very reliable despite the abuse of continuing to run it while misfiring, and I'd like to eliminate the misfiring once and for all to make sure it continues to be reliable (and fuel efficient).
Thank you for sharing.

How's your oil consumption? At that mileage, my engine started fouling plugs in some cylinders with oil. All I could do is keep changing the plugs in those particular cylinders. It still passed emissions, BTW.

Not much oil consumption, just changes. Lots of little grungy leaking everywhere. No fouling of the plugs; they look good.
It needs a CA smog inspection, and I doubt it will pass like this.
I'm guessing it's time to replace O2 sensors. But I wonder if it's common that the electronic module that acts as a distributor cap goes bad, causing misfiring.
Is it common to use trial and error replacing these expensive parts?

Trial and error is always the method for repair, unless you get the computer to throw you a code directing you. With an engine this old, trial and error is bound to happen to you, but darn near everything on it is old, so replacement of anything is not such a terrible idea.

you need to give a little more info. on this truck such as what year is it, and what size engine does it have. is it 2 or 4 wheel drive?

i had a 97 with a 4cyl. 2.3 engine with one plug misfiring when i put a code reader on it the code wasn't even in my book, but it turned out to be my crank sensor. you might want to check your plug wires as well if you havn't already done so. before you replace the parts. check the compression to make sure it is good on the misfiring cylinder. i used to be a certified mechanic back in 1975 but didn't keep my certification so i am not up to date on a lot of these computerized vehicles but i do know some things about them. hope this info helps.
#2694 of 2995 2001 4.0L Timing Chain or Belt??

I have almost 100,000 miles on the truck, does it require belt or chain replacement now or not??
