Engine Issues or Sumthings Up.....

Hey guys I went fishing today and as I was coming off the beach the truck started to do the bucking and etc...... Too me every time it bucks I can smell oil being burnt up. Like oil you smell with a bad head gasket. I dont see smoke out of the muffler or under the hood.

As I got off the beach and on the road, she did it a few more times the bucking. Engine wouldnt start, open hood and play with that 3 prong connector every1 says is the issue.

As you hear the engine buck it sounds like a dieing engine, one that isnt getting gas, or something is in the gas, bucks, knocks, kicks, clanks, etc... i dont let it go for a few secs before shutting off. And then try to start, she does what I just stated and dies instantly

Then as I was driving home, I lost engine HP and power. She was like riding on what I would say 3 mb 4 cylinders. I would rev the engine she sounds like a dieing car, and an engine trying to gasp for air, car wouldnt go over 50 mph, if I tryed to gun it she just high revved and car would go nowhere, like she was in neutral.

No Check engine light on dash, Just did tune up months ago replaced everything I thought of. oil change on the regular, dont see any oil leaks on floor. Only flashing light I see is on that Cpu diagnostic with the pic of truck n small square in engine bay is flashing. Dont know what that means.

Any ideas before I bring to shop? Thanks guys

I would start with checking into your o2 sensors an the wires leading to the PCM. Did you kick up a lot of sand on the beach? When was you last tune up? Any codes?

Sounds a little like the fuel pump relay. Swap it out with the horn relay and see if it improves. Are you sure it's not fuel you are smelling?

The three prong connector? There are three connectors on the PCM that give a lot of problems. Wiggle them while the engine is running and see if anything changes.

the 3 prong PCM thing is False. We sat there for 1hr straight and played with them plugs Nothing. Not sure why the car bucks and does what they say, but to me its not the PCM

Fuel Pump relay, I will replace

But why the Horn Relay??

Could this also be from a Clogged Cat or exhaust?

When you Rev the Vechile, in Neutral you hear the engine gasp for air, a deeeep rev it has, and itsnt higher than 4200 RPM

Car cannot go over 55 MPH or it just High revs and is like in neutral.

Car has No Low End power period!

Not being able to go over 50 would indicate a bad cat.

Did you bottom out on the beach? Look for exhaust damages......? Are we getting the whole story here? Did you see if it could float or do some deep sea exploring?

Because it is not essential to get from point A to point B. Saves you from buying a relay you don't need.

BTW, people here want to help you and are not out to get you. JS didn't deserve what he got and you should apologize. I'm done with this post.

The PCM sets fuel mixtures for the engine performance using the o2 sensors. Some guys have ran their rigs without a cat in hopes of better exhaust flow without any adverse effects. It probably would run alot better than it's running now.

A new cat that has the down stream sensor port runs about $150.

Zee was trying to determine if your problem was ASD or fuel pump related.

But what does his statement mean?

And why replace the Horn relay?

I also know how a cat works... Also I can get a cat for 69 bucks.
