After a stop, when pressing the gas pedal, the truck doesn't "go" accordingly, it just goes very slow and after pressing and releasing the gas pedal several times the truck picks up speed. I don't have this problem when in reverse. The truck has showing the " check engine" message a couple of times. thanks in advance for any info you can give me on this issue. You can contact me directly at "thepowerpc@yahoo.com".

 

What check engine diagnostic codes are you getting?
The whole point of having them is to point you at the problem.

 

No code, is just the light that comes on the panel. Is there any instrument that I can buy to diagnose the truck problems or, to keep it in top working condition (tune ups), at home?. Thanks again

 

Being it's a 95 you may be stuck in OBDI-land. The codes are not quite as specific as OBDII, but the up side is you may be able to retrieve them with a jumper wire-DON'T GO STICKING WIRES INTO THE TEST PORT UNTIL YOU VERIFY YOU CAN DO IT!

If the check engine light is flashing it could mean that the problem is potentially fatal to the motor.

Not bagging on you but it sounds like your wrenching time has been a "limited experience" for you-but that's ok.

My first thought from what you discribed is your cats may be going bad, try this link and see if it fits. http://www.aa1car.com/library/converter.htm

You may also want to pick up a Haynes book for your truck, almost any auto parts store sells them. They are not the best, but it will get you started.

And yes there is a scan tool to find out what the codes are-just make sure you have the right one for your vehicle( OBDI will not work on OBDII and vice-a-versa).

Good luck and post what you find.

 

I'll see about the "retrieving" part, i'm not a mechanic so, I'll do my homework on this one. The check engine light is not flashing. My "wrenching time" yes, it has been a limited experience. I'll check the link about the cat. I have the repair manual, I'm reading it. I'll check on the OBDI scan tool. By the way, if it was the cat, don't you think that the same problem would happen when going/switching to "reverse"?

 

Not necessarily, when you are in reverse you are only backing up for a short distance, plus I think that reverse is geared lower. And you don't "gass it" the same as when you pull away from a stop.

The cats was a guess-without DTC that is about the best anyone can do.

On tge code reader if you aren't in Calif. then you can have them read at Auto Zone. Don't take their word as gospel on what is wrong and get the exact p0 numbers if you have OBD II.

 

For OBD-I

Will not work with OBD-II

 

I don't know about the "gearing" and "gassing" difference going forwards or backwards, but is a point that I'll dig into. By the way, reading the repair manual I just found that The 1988–95 gasoline powered Ford vehicles employ the fourth generation Electronic Engine Control system, commonly designated EEC-IV, to manage fuel, ignition and emissions on vehicle engines. I'll take the truck to Autozone in a few mins.

 

EEC-IV uses the OBD-I protocol. 96-up vehicles use OBD-II. The exception to this is that some CA spec 95s are alleged to be OBD-II.

 

I'm still digging into this. Called Autozone but they don't do engine diagnostic in California. I'm gonna try a trick that I found through the link you gave me: "http://www.extreme-check-engine-light-codes.com/Ford%20OBD1%20Decoder.htm"

 

I just got a text message from somebody with the same problem and he told me that he had to replace the "gas pedal" which is electronic ($700 bucks!). Anyone have a theory about this?

 

Ignore that e-mail. Your throttle is mechanical.
The Throttle Position Sensor is electronic but it doesn't cost $700 to replace.
DO NOT replace it without verifying that it is the problem.

Pull the codes

 

I read about it and it seems like you are on the path, now, I just need to find the "Throttle Position Sensor"

 

On the side of the throttle body.

DO NOT just randomly replace it because somebody told you it could be a problem. Pull the codes; that's what they're there for. You can check the output of the sensor if you want. The Haynes manual should have instructions.

 

Yea, no worries and thanks for your advise. I just came back from O'reilly's and got the "Ford Code Reader for OBDI", I'll plug it in in a few after I read the instructions on where to plug it. I'm not using the Haynes manual, I'm using the "Auto Repair Reference Center 1*
