Help

1995 2.7 auto 4x4
What happened... Truck died while driving.
Had no spark
Changed distributor
Truck started right up!
Tried to drive...truck sputtered and hesitates!
Cel came on code for TPS
New TPS
Still runs like crap! And getting same code for TPS
Took to shop...
Shop says its the MAF. Drove home with MAF disconnected and truck will accelerate!!!!
New MAF...runs same! Like crap
So...I changed fuel filter...nothing!
Got another code...crank sensor
Put new crank sensor on...still!l runs like crap
New code cam sensor...well it doesn't have one...guy at shop said new distributor is bad....so I returned it and got another one....nothing runs the same!
So I put a used computer in and still runs like crap!!!
Here are the symptoms as of now:

Starts right up
Stumbles and stalls up to 4 to 5k then runs fine....
Any help is greatly appreciated!!!!!

 

Sorry I forgot to mention I also put new cap rotor plug wires and plugs....

Thanks!

 

I forgot more info. Truck has 190k and only goes to 5k while parked not driving under a load. Driving is difficult as you can maybe go 40 mph if you ease into it.
I've owned the truck since new so Its my baby.
Thanks again for any help!

 

Does it run better when first started from cold? Edit: does it run good cold then like crap when warm?

 

Yes, a little better at idle. Otherwise the same studdering and stumbling.
Thanks!

 

Good spark plugs?

 

Yes I presume I used copper oem from AutoZone. Gap at 32

 

So, it runs good first thing then when temp rises like crap?

 

Honestly runs like crap no matter what. Lol

 

Igniter comes to mind with no spark but I don't know if you have one. Edit: stuck egr made my old truck run like crap. How old is the battery?

 

Thanks for the reply!
Battery is new also. I may replace ignitor as it is cheap. Guy from shop stopped by this morning before work and put his computer on it again. It is telling him truck is running rich???

 

Vacuum leak, maybe

 

I will spray some starting fluid around the intake after work and see it the engine reacts...it all stems from when the module in the distributor went out????

 

Spark plug wire not seated correctly or faulty wire? Cracked spark plug? Those are just a few more ideas

 

I will double check those. I am also going to check the timing again...
Thanks!

 

Ok, instead of throwing parts at this, maybe you should think about what happened a little more.

The truck died while driving: Does this mean that one second it was running fine and then it just shut off?

All of these issues make me think this is electrical. If the truck was running fine before it died, I doubt all of those things went bad at the same time. How good is your battery ground, engine to chassis ground, etc?

 

Thanks for the reply. Yes, truck was running fine. It sputtered a few seconds and died. It would not start. So I pulled a plug and was not getting spark. I then changed the distributor which comes as a unit with the module. It started right up but has not run property since....I am taking it back to another shop next week for a second opinion.

 

I FIXED it!!! I manually adjusted the timing like I did on my old Porsche. Manually it was about a tooth clockwise off. So I adjusted the rotor counter clockwise one tooth 1/8". But......it is now giving me a po336 which is the crank sensor. I just put a new crank sensor in! And if you stat it and let it idle on its own...as soon as the rpm goes below 1000 it dies...but if you manually take the idle down by using the gas pedle you are OK???
