It's funny, drives okay one time and the next it stutters and sputters.  I checked the codes and it just has 12/ 45/ 55.  Should have 12 for a while since the battery was disconnected, 45 is for the OD unit sensor, and 55 is the end of codes.  I did put the deep trans pan on already, changed filter and fluid, and changed the cooler line too.  I took the wiring harness off the V6 and cleaned and rewrapped it.  Only problem is there is no TB temp sensor for V6 and I don't know if that would affect it.  I ordered the other injector with the code from Mat.  Should be in by Saturday.  Also ordered lower ball joints too. 

Three things I want to try:
1)  First the new injectors since it's the easiest.
2)  Second is swapping the whole TBI with the V6 one. 
3) Change out the wiring harness with the V6 harness.
The reason for swapping out with the V6 items is to eliminate problems with known working items.  If it's the issue then I can deal with it.

I am really getting worried that it won't be resolved by end of April.   :(

I think it's just pissed its not in a 4wd anymore  :laughing7:

you just need to show it who's boss and that this 2wd rig can be a lot of fun

otherwise we will have to tow it down to hidden falls to work on it there over the weekend  :steeringwheel:

Just getting a little down.  Once it's up and running good, I won't even remember all the hassles.  I just can't seem to isolate the problem.  Really frustrating.   :confused2:

I don't have anything to use it on any more.  My father in law is pretty sick so I might be out of pocket.  I'll see if I can't get it boxed up and on the way tomorrow.

It is on the way by Fed Ex.  They were the first by the office today.  Sent by regular freight.

Changed the rotor and cap today.  The old one was cracked on the side prolly from chain on the swap.  The high revs sounded really good and promising but still had the surging with part throttle steady revs.  I wanted to change the wires too since some look gouged and torn.  All I could find around town in 8mm was Accel.  I've used them before and they are junk.  Not liking the gay yellow either.  Guess I'll be ordering some online.  Really want the 8mm to take advantage of the MSD Blaster Coil. Also checked vacuum and it's solid steady at 25 inches.  Heading back outside to change the harness and put some old 7mm's on to see if it changes anything.  Determined to succeed   :035:

sure you have seen this, but I just saw it and wanted to pass it along:

http://ramchargercentral.com/vehicle-help/confirmed-fixes-cheat-sheet/

a few idea's there. wonder if the v6 diet and hall effect sensor can be swapped? maybe just the sensor and not the dist to avoid timing issues?

Also check that wire connection:

most 1988 to 91 running problems can be traced to wiring [ the connectors at the back of the right valve cover or the connector on the pcm its self ] or a bad PCM

worth a try maybe?

how did your test today go?

could try checking the old spark plug wires with a digital multi meter. i think there is suppose to be about 12ohm's or less of resistance.

Swapped out known good wires and still surges at a steady part throttle.  Full throttle blasts sound great.  Gas tank filler neck seal came in today and changed that out and put a new longer filler tube hose. 

Edit: Thanks for the link.  I took a gander at it and there was a guy with a similar issue with the hesitating at part throttle and good at WOT.  He tried changing the hall effect and made no difference but ended up swapping out the distributor and fixed it.  Gives me 2 more ideas.  Another thing was mentioned though.  He had the original injectors that had the pins on the bottom with 2 O-rings and another set from a van that had the spray holes with only 1 O-ring.  That injector you sent had the holes and the original has the pin.  At a glance, they look the same and both have 2 O-rings.  Guess I'll find out soon enough if it fits or not.

On another note, the FSM mentions the hesitation/ surging while driving and lists possible problems as distributor or injectors.  Could go either way.  Will that fancy doo-dad your sending figure out which way to go?  :icon_scratch:

I don't think a faulty throttle position sensor will always throw a code. That might cause the problem. I think it can be tested with a meter.

it should show you the readings... and if you reeve it up and one of the readings goes whacky then you will know. It will show you what readings the sensors are giving to the computer... RPM etc etc.


Rock auto shows different part numbers for the v6 and v8 distributors... they look similar, but I am sure the Hal ring is different between them. Hopefully its ok It looks like the hal sensor off the v6 might be interchangeable to the v8, worth a try?

I also see the v6 and v8 fuel injectors are not the same part number, so it could be starving and anything but WOT?

Did you order the other injector? You could maybe try a combo of the new injector I sent and 1 of the old ones, maybe 1 was better than the other?
