tps experiment make sense. the other sensors really only fine tune things, the tps is what tells the computer to add fuel. tps reading 23% = fuel enrichment 23% +/- whatever the values from the other sensors tell it to do based on the fuel map.

did the temp sensor have any sealant on it? if it didn't come with any you'll need to put teflon tape on it and reinstall it. if it did have some give it a little more oomph.

 

Great news and bad news, got the cap and rotor replaced (old ones looked like ****, calcium on each tendril inside the cap, rotor had carbon and calcium build up, the spring in the center was stuck).. Test drove for about 10 - 15 minutes and it ran like its never ran. Stop and accelerate worked like it should have all along.. Turned left onto a main road to head back home and it sputtered and so i stopped and gassed it again and it sputtered and than caught itself. Made it home fine, was just wondering if its possible its trying to acclimate to running good again or if the problem persists?

 

Also threw a bottle of techron in it to hopefully clean up the injectors a little..

 

Drive it for a few days, see what happens.

 

Still running fine or rough? If rough, maybe double-triple check your connections, everything plugged in nice and tight?.

 

Well it idles good and like i said it accelerated good until that last push home. I dont feel that slight surge from 800 to 900-1000rpms any more. It stayed at 800, until i drove it and parked it and than it idled at 900.

 

based on everything you've said so far, i would say the ol' girl is just suffering from a bad case of lack of maintenance. i would either check the fuel pressure or replace the fuel filter and pray. you're all caught up on the spark side, so at this point it's either fuel or wear. i would guess fuel since it cut out going around a corner. i'm thinking lots of sediment in the filter or the tank. the filter is the cheapest and easiest next step.

the techron should do a nice job cleaning up the injectors.

if the filter don't fix it, you'll need to check the fuel pressure at idle and while the engine is revving. 176k is a good long life for a fuel pump, so i wouldn't be shocked if it can't keep up with the engine anymore.

 

Well to my understanding the fuel filter is tied into the pump mounted inside the gas tank.. I was trying to avoid this fix like the plague haha. But yea, im sure the fuel filter needs to be replaced, truck is 20 years old and a lot of the parts I've replaced were stock. I didn't even think of this at the time but when i bought the truck i didn't ask how long it had sat and I'm thinking the half a tank of gas went stale and may not be combusting fully anymore. Either way i suppose its probably best to replace the fuel pump/filter.

 

Test your fuel pressure before just replacing the pump out of hand. That is not an inexpensive endeavor, and if it isn't the problem, you just wasted a couple hundred bucks.

If you think part of your problem may be related to old gas, drain the tank, and put in some fresh, drive it for a couple days, and see if things improve.

 

Didnt catch your comment heyyou, sorry. Well i picked one up online for $50, should be here the 12th (made sure it fit my tank and not the 35gal) so atleast i didn't spend the $218 autozone wanted. I'll update you all whenever i can get the pump replaced.
