91 Bronco XL 4x4 :: Jumping Issue - Almost Stallout
91 4x4 Automatic Ford Bronco XLT
Motor: V8
Mileage is: 136,000
Year: 1991
In the past few weeks I noticed a my idle has been poor at times - really inconsistent. Here are some details:
- When I first start up and drive off it almost feels as if I am going to stall out.
- When I get up to about 45-55 and tatking off or just cruising on the highway I will get will - what seem to be - power losses. No stall, but just kind of jolts like light kicks (like losing power or gas shrortage feeling). The all will be fine for 5-10 minutes again.
- When I am idling at a red light my RPMs gauge is "shaky" like I might stall out - it does not happen all the time, and I have not stalled fully yet.
What have I done to try to fix it:
- Changed the fuel filter
- Had a new tranny put in (not becuase of this issue), but I did notice it started after the tranny work was complete. It was very recently.
- Had a tune up 10,000 miles ago
- Recent oil change
If anyone has any ideas where I should check or even what the worst case scenario could be, please let me know.
I'm looking for any recommendations or suggestions as to where I should start to look.Thanks,
RK

The first thing I was going to say was fuel filter but you've done that already.
Have you checked your timing?
How bout a miss?
I know you said you recently had a tune-up, but what all did that entail.
Maybe one of you cylinder's isn't firing; or firing inconsistently.
Did they change your rotor cap with the tune up?
Maybe you have a bad connection or dirty contact on one of them.

make sure the plug wires are routed properly and not touching each other. and double check the firing order as well. its easy to get them mixed up. your tranny is probably the e4od, have you tried pulling codes www.fordfuelinjection.com will show you how.

You know, it really depends on they way they took it out. But, it could have been during the tuneup and the tranny problems you where having would mask it. Mine started when I put headers on, I labeled the wires and sure as crap, they had been on wrong since I bought the truck. But the increased performance, seemed to cause all kinds of issues.
Good luck.
Good luck.

Hold on now...do this check first...
http://www.autozone.com/az/cds/en_us...rInfoPages.htm
I am not sure whether you have a 5.0 or 5.8, both are here...you can't screw it up. You are just looking.
Then, goto www.fordfuelinjection.com and pull the codes...a cheap $3 analog meter will work, just get an extra length of wire.
1/2 hour...max.

He did mention only changing one fuel filter... He could try some seafoam in the tank, could be fuel pump pickup sock, supply or return filter...put some seafoam in the tank? cheap and easy check, clean up some of the fuel system...

Hey Ya'll
Thanks for the helpful insights on what the issues might be.
After doing some inspections, and having a lookover by a Ford vet, we were able to to determine it was a spark plug that was shorting out.
It looks as if the plug was melted by:
a) the spark
b) touching something hot
I am not sure how the melted area came about actually - I should have asked specifically. The internal wires were exposed on one of the plugs.
Anyhow ... going fishing

Does anyone have a Bronco maintenance checklist - routine tasks to do on high mile (140,000K) Bronco?
I just want to maintain it a long as possible and running strong. I always do oils changes on time, tranny fluid, etc..
Just wondering if anyone had something?
Thanks for the assistance
