Falling on its face

Alright so after having my throwout bearing shear itself in 2 after raping it the other night in a mud pit, I had to replace that and the clutch. After going through all that the engine decides it wants to randomly fall on its face during accelleration(sp?). Even during coasting it will decide to drop off down to about 100-300 rpms for a few seconds then come back up. I have no idea what is wrong with it this time.

how hard did you thrash it in the mud? if there was alot of water/mud thrown up in the engine bay, some of the electrical parts that just love water could be unhappy with you. first thought is tps, maybe distributor. are you throwing any codes?

definitely get those codes checked. auto zone is your friend. you could have new problems relating to the mud playing that's causing this problem.

Did you make sure the plugs were gapped at 35 thousandths? Ran into that problem myself not too long ago.

Yes I did gap the new plugs. The plugs I pulled out were gapped at .047-.043-.025-and the fourth wouldnt go on the gauge. I went and got my codes scanned and it was throwing 7 codes. misfire on cyl 1, 3 and 4, throttle position sensor. and a few more I cant remember. I replaced TPS with no change in how it ran.

Any help? The bucking and stalling in traffic really isnt humorous and not safe at all. I feel like driving it off a cliff

what about your O2 Sensor. I ran into the same problem a while ago. I replaced plugs wires, TPS and O2 sensor and the problem was solved.

I replaced my o2 sensor (1 of them) less than 5k miles ago. and I got my codes run again today and this time I only had 1 it was code P1391-manufacturer controlled ignition or misfire. No idea what that means or how to fix it though. But I can tell I will get into an accident or possibly kill myself by being hit by the way it runs right now

as best as i can find, your cam position sensor is having some issues. could have gotten wet and is shorting out. check connections there and make sure they are good. you may need to replace it.

Uhh..... .....Ill look around for it. But its wierd how it happens. In 1st it will happen all the time, but the other gears it will happen at around 1800rpms and up. I cant drive more than 50 mph. Its really frustrating and it makes me not want to drive it or go anywhere

Ah yeah I got it. When I cleaned out distributor cap and rotor button. the sensor(camshaft) I guess sits right there on the distributor was covered in mud. Ill try and see what happens after I clean that off. Ill check to see if my friend put the crankshaft sensor back in right too

I think with that error there's also a possibility that your distributor could be worn out. When you put new plugs in did you replace the distributor also?

Okay, that's what I was talking about. Sorry if I wasn't clear.

But wait. I changed the cap last time I replaced the plugs like 8k miles ago. Would it go bad this soon?

So I found out that when my friend but the crankshaft sensor back in the tranny he forgot a bolt and it was moving freely in and out of position. So I put it back in place and tightened it down and that didnt help. Im going to check out the camshaft sensor tomorrow.

Actually by me tightening the bolt back down it did help. It completely fixed the problem. I just hadnt drove it around long enough last night for it to send the right signal to the computer. Thanks to everybody for all their help. With everything Ive replaced this thing is running like a champ
