New to this forum have clicked in every now and then trying to fix my truck. I have a 1994 5.2 4x4 reg cab long box with 227,*** miles.
Things replaced right of the bat: topped of antifreeze and brake fluid, 4 new tires, few trim peices, and transmission fluid/filter and oil.
From the moment I saw the truck the only known issues were leaking transmission fluid and spongy brakes. It fires right up all the time, in any weather.
When the truck started acting up I was driving on the highway 55-60 mph and low on gas. As I cannot recall all that happened, Ill try my best to give all the information I can. It bucked and sputter as though it was running out of gas. Pulled over, turned it off and was waiting to have a gas can brought to me and decided to start it on a whim. It fired right up. I decided to drive on to a gas station (3 miles) Noting the truck would not go over 3000rpm. Put half a tank in and some injector cleaner, no change. Not going over 3000rpm was not a significant hinderance at the time, daily commute round trip is 30 miles. Half of that is gravel and fastest I go during the trip is 60mph. It slowly got worse, wouldn't go over 2500rpm. Now it will not go over 2000rpm.
Not going over 2000rpm is an issue, as I can barely get up to legal highway speed. Things I have replaced or checked since include: fuel pump replaced, plugs/wires, oil. Checked or swapped with known good parts: tps and map sensor. Compression on all cylinders, worst being 110psi best being 150psi and the rest fall between. Unplugged injectors one at a time and observed the engine bogged downthe same on every injector. Removed catalytic converter to no avail. Only codes showing are 12, 37, 34, 51, 55. The check engine light does not remain on after the bulb check.
So for a final breakdown the problem is:
Won't go over 2000rpm without sputtering and bucking but won't die. It does this in any forward gear and park and neutral. Cuts out quite a bit in reverse, still does not die. It idles great, fires up great, at a loss up to this point. All plugs are firing.
