Wassup guys, i was doing a little trail down by the river, and drove my truck off into a pretty deep hole. The truck stopped about 2 feet into the hole and shut off. We tried to start it but ended up having to trailer it home. I pulled the plugs and turned her over and spit all the water out. There was small pieces of sand in between my plugs so i blew it out and reinstalled the plugs. She started back up spitting and sputtering and it threw a code for the TPS. I replaced that and the air filter, and its still running like s**t. I have no low end power whatsoever and i cant even take a hill and hold speed, i have to drop to 4th and sometimes 3rd on hills i used to could take in 5th without problems. Its skipping and sputtering and i have "dead" spots in the rpm range...it takes alot of clutch slippage to even take off. I have no more codes and havent a clue on where to start. I flushed the oil 2 times and ran about 4qrts of clean oil thru and finally replaced with my regular Mobil 1. Any ideas on what else i should do, and what could be causing me to have no power?? Its not smoking, and all the fluids are fine( ie: no oil in coolant or vise versa)...Please give me tips!!!!

 

Clean the MAF sensor.

 

aight ill try that, i was thinking of seafoaming it as well...btw ill have some pics and vids of the situation up tomorrow

 

DON'T PUT SEAFOAM IN THERE NOW!!! Believe me, its probably saturated enough already. What you SHOULD do is change the oil and filter tonight too. If it comes out looking watery or otherwise nasty, change it again in a few days. I'm not sure if it applies to your truck, but I've heard changing the gear oil in the diff might be required if the water was higher than the breather tube.

And yea, the MAF is probably a major culprit right now. It will probably run better unplugged. The computer will run in on non-MAF mode which sucks but at least it will work.

 

i already flushed the oil and changed it, ive driven it about 45 miles since i changed the oil and the tps...i changed my rear diff also, and am goin to do the tranny friday when i get paid...im just trying to figure out why i have no power...its not knocking or doing anything funny, and before i sunk it i didnt have gobs of power either, ive been trying to figure out whats wrong with it...it kinda surges when u hold it steady

 

put some gumout with regane in your gas tank.it will clean injectors

 

Compression check to see if the valves are bent?

 

Your engine is toast, been there done that.

 

valves could be junk because of the crap that was sucked into your engine. compression and leak down test.

 

Compression test.

If it passes, maybe throw some more money in it to get it fixed.

If it fails... drop it like its hot. I'd be surprised if the cost to fix it isn't about the same as or more than the pre-damaged value of the truck.

 

162 cyl #1, 160 #2, 160 #3, 165 #4

 

lowest reading cylinder must be within 15 psi of the highest reading cylinder 100 psi minimum

 

so i should be good right? the chart kinda confuses me lol

 

Your compression seems to be ok. If they are within 15 of each other then I think you are ok.
