no power over 2k rpm

i'm looking at buying a '95 reg cab w/ 5 spd. it only has 68k miles, but when i drove it there was no power over 2k rpm. i'm not sure i could get it to 3k if i tried. seemed like if i gave it over 1/2 throttle it just wouldn't do anything. the owner hasn't driven it on the road since at least december...though he said he started it a few times. could this be old gas? air intake blockage? fuel filter clogged? or am i looking at something more serious?<br><br>thanks in advance for any help

Re:no power over 2k rpm

If it has a catalytic converter, that could be plugged.

Same problem I have with my 95 and my cat has been gutted.<br><br>Just about 2000 - 2200 rpms, my truck falls flat... no power beyond that.<br>I too, dont think I could get my truck to 2500 or 2700 rpms if I wanted to!<br><br>Im thinking that its the stock governor doing this. A 3000 GSK would probably fix our issues.<br><br>Rich<br>

Re:no power over 2k rpm

Is your throttle cable pulling the linkage all the way?
Or it could also be a timing prob.

Re:no power over 2k rpm

GSK = Governer Spring Kit.<br><br>Yes, Its an aftermarket item that raises the point at which the governer starts to defuel the rack in the pump (I think thats how it works).<br>Anyway, it allows our trucks to turn more RPM's before the fuel is choked back.<br>I believe the stock governer is designed to start limiting fuel around 2200 rpms? Please correct me if that rpm number is incorrect.<br><br>There are 3000 GSK's and 4000 GSK's.<br>If you decide on the 4000 GSK's you will have to upgrade the valve springs to prevent from floating the valves at those rpms.<br><br>Rich.

Re:no power over 2k rpm

Dedar:<br>You might also check the fuel filter and the overflow valve. A plugged filter will perform the way that you are describing.<br>george

Re:no power over 2k rpm

Does anyone know the approx RPM that I should obtain at full throole in Park. '96 12v 5.9.<br><br>I seem to limit around 27-2800. I had the throttle linkage changed last fall - rust in the ***** caused sticking - and I think the lenght may be wrong. <br><br>Hate to take it to a dealership.... :'(<br><br><br>

Re:no power over 2k rpm

It should go atleast to 3k when not in gear. All the ones I have seen stop there. get the 4k gov kit and end all the problems <br>DM01

Re:no power over 2k rpm

I had this problem twice and once it was a dirty fuel filter. I hate to admit that cuzz I am pretty good and all the maintance. The filter was plugged.I really don't know where I picked up the trash, but I did. I would run to 85 and it would quit. Start losing speed.<br><br> Other time the ole FS-OS was not working properly. That stands for Fuel Shut-Off Solenoid. It was not pulling all the way and letting the throttle move the fuel. Changed that and has not happened since.<br><br>Timing, I don't see how that would do it. With that milage seems it's pretty well set.<br><br>That's what I think anyway.<br><br>..Preston..<br><br>..PT..

Re:no power over 2k rpm

Both my 95's have never hit 3000 rpm since new. Both will top out around 2500 or 2700 and still do.<br><br>A 95 with only 68000 miles probably needs a valve adjust, filters changed, pre filter screen cleaned and get rid of the resonator.ALso, put a free breathing air filter in, such a s K&amp;N. Your rpms should get over 2500, but, in my opinion, you'll only see 3K with a govenor kit.<br><br>Gary
