Brand new it was a complete dog.
I couldn't even pass on a two lane road unless I backed way off the car ahead to get a running start. Fortunately for me mine was only stock for 4000 miles, heck with the warranty.
Now with mods if I floor it at 60 mph I can be breaking 80 easily by the time I pass another car.

 

revs real smooth. brought it up to 70mph at 2700 rpms, it was still going, but really, really slow.
i thought about the waste gate being open, but havnt delt with one before. tryed moving the acuator arm, but didnt budge. i wacked it with a wrench, but it didnt make a diffrence when i drove it agian.

can u manually, open and close the waste gate on a hx35/12w? this would also explain no spool up, if this thing was open, right?

thanks, Bob

 

When the wastegate fails it's almost always closed position and will give you no trouble. The spring that holds it closed is very strong.

Your description sounds like either someone has messed with the AFC spring or the diaphragm under it is torn. You can tell if it's been messed with if the bolt at the very rear of the injection pump doesn't have a tamper indicator wire though it.

 

What about the fuel heater screen? Could that be clogged up and restricting fuel flow to the injection pump. I know mine was really nasty and made a big difference when I cleaned it.

 

thanks every one.

i am going back out there tomorrow, and take a closer look at the truck. and my tool box. the dealer wanted me to dig into today, but i didnt have any tools. plus i am not that familar with the p-pump. but i have a filling i will be soon. what gets me is my 1st gen runs like a demon compared to this 95.

so, this is what i will look at.

AFC on the pump.
heater screen
W/G actuator.

and relay all this to the dealer to get checked. including cat. muffler

how hard is it to fix the track bar? upper and lower ball joints are going as well.
thanks every one.
keep any more ideas coming please.

Bob.

 

Trac bar is a cake walk. Ball joints always stink. Honestly if the dealer cant fix it and is willing to sell her cheap I dont think that I would spend much time fixing there. Strike the deal and fix her at home. If the IP was gone through and is fine I bet the problem is a cheap fix. Good luck

 

i have heard stories of the TV cable causing these trucks to be "death trap slow"
possible that its worn out or out of adjustment??

I would assume that the 95's have a throttle cable. With a little age they stretch like a rubber band, the one an my 96 did. Check that your getting WOT.

 

Not if the arm happens to hang on the bottom of the plate it won't! Been there seen it happen!

 

maybe he had the plate out and put it back in further to the rear than it was?

 

TV CABLE?????

 

throttle valve cable is what i have always heard it called, hence "TV Cable"

What about fuel shut off solenoid, my 97 was a dog with no spool up and NO power, very very slow acceleration and a almost dead pedal because the solenoid came apart and would pull lever up all the way. Easy way to check is to disconnect the end of the solenoid form the arm and wire the arm up. Then start it up and drive.

 

Stock 95 autos really are just that bad. Mine was 100% stock when I got it, except for no cat and a flowmaster muffler. It could barely get out of its own way.

 

does the truck have a e-brake on it?
