93 Econoline/transmission affecting engine?
93 Club Wagon/econline V8, 5.4
I think the transmission is going out (again), it slips a little but the big thing is that it bucks (like it wants to stop then go forward while driving)
Someone told me it might be the torque converter.
The engine stalls sometimes and sometimes it wont start. The van runs great on the freeway.
My question is, can the torque converter or transmission cause the engine to stall even when I put it in neutral or park?
It feels like it is missing really bad but this only started since the transmission problem started, that is why i am asking if the transmission could cause it to feel like it is missing.
Transmission has been rebuilt 2 times in around 9 years, I just had the plugs, wires and tuneup done and it does pass smog with no problem. It does have an oil leak and if I dont keep it full it will not start unless I put a quart in.
Thanks.

A '93 would have a 4.9, 5.0 or 5.8, not a 5.4, that didn't start until '97.
When you shift into reverse, does the engine stall?
If your have the E4OD transmission, the engine running poorly will effect the shift points, if the transmission has problems, it will effect the engine. Both are "controlled" by the ECM.
I'll let the Transmission guru give you more details about this, but please check what engine and transmission, and year you have, and post back.

No, it does not stall when shifiting into reverse at all, and runs good in reverse. (Not that I drive very far in reverse, lol )
The year is 09/93, It is a E4OD, I just double checked and online and it is a 5.8, the ford vin tool shows it as a 1994, but the tag says 09/94.
Thanks.

And, a 5.8 would be correct for the '94 model year.
The good news is.........the '94 model year was the first year that the engines got the roller cam.
My old '94 got parked with 328K on the clock, and never did any work on the internal engine, or heads. Body just gave out, and needed something a little better, box wise (cube van) It was still starting and running, until I started to steal parts off it for the '92
The reason I asked if it stalled when shifting in reverse, one of the things that happen with mine was stalling when shifted into reverse, and then 2 weeks later, I was installing a re-man E4OD back into it, something about when you go into reverse, a bad tranny will stall the engine out. I was also getting the high speed shutter once in a while before the tranny died.

One thing I forgot to post is that when I am idling at a red light, it feels like
its going to stall (sometimes) and it has a few times, But... If i put it into
neutral or park while waiting at a red light it does not stall, or feel like it is
going to. Thats why i was leaning towards a transmission issue.

If you have a OBD scanner, make sure it's for OBD I, or ECC, not one for '96+ that is OBD II.
Your problem is while engine is under load (in gear) it want's to stall.
Stalling at stop/idle could be more of a EGR, fuel delivery or Vacuum problem.
Vacuum leak would make the engine idle higher RPM's than it should, and could cause stalling (sucking in too much air)
EGR problems would cause the engine to "choke" and stalling problems.
Also, check your fuel delivery. Pump pressure at fuel rail, FPR, and it might be as simple as changing the fuel filter.

I had a tuneup done a few months ago and the fuel filter was replaced then.
And the mechanic said he did a smoke test and did not find any vacumm leaks.
I did have a rough idle and after the tuneup it went away, except for a slight miss.
I will post again after I check it with the scanner,
Thanks.

I did the test (OBD1), Not running and Running.
It passed the Engine off test
But Engine running test I got
536 - Brake on/off circuit not activated
632 - Overdrive cancel switch not activated during engine test (This is Probably because the switch does not work)
I did the tests 4 times, While I was doing them the engine was idleing very rough and missing so bad the van was swaying from side to side.
Like i posted before, the fuel filter was changed when I had a full tuneup done on it a few months ago and it did help with the rougher idle I had before.
What should I look into next?
Thanks.

Plugs, wires, cap I think thats its,
But now I have a bigger problem,
Now it wont start, It turns over with power but I dont hear the fuel pump like I always have and I heard it every time the tests were done.....
And the oil pressure gauge doesnt seem to be building pressure like normal.
I know I have plenty of oil, I just added a quart the other day.
Could this computer have damaged something?

Unless the engine is running the oil pressure guage won't work,

I meant when I am cranking the engine. I usually watch it build pressure.
I just tested the fuel pump fuse and relay and they are both good but I still dont hear the shuish sound I usually do.
