Just bought a 1995 Bronco XLt. 105,000 MILES.

Transmission has been rebuilt, new driveshaft, new fuel pump,......

Lots of goodies, but the truck on the highway seems to be sluggish.

When I pull off of an exit I have to floor it to get it up to 55-60mph and it does not appear to ever want to go 65mph or faster.

My question is.... is this normal? Or do I potentially have an issue?

Thanks for the help.

What engine?
Tire size? Gears?

What are you used to driving?

Acceleration in these things is not very great. 0-60 should be about 10 seconds. My 94, with 150k in 2007 would still max out the speedometer

my 86 will still get up to about 90-95 (don't recommend).

There is something going on. gearings, engine, hard to say.

what engine/trans/tires/gears would help.

Is it redlining at around 65?

also, if it is an automatic, do a manual shifting starting from 1st, and verify each shift change.

Yo Baker,
Welcome!
Assuming you have the E4OD AutomaticTransmission;

OD Transmission Control Indicator Light (TCIL) is a LED with an overdrive on/off switch at end of the Transmission shifter stalk; flashing OD light is an indication of a transmission related trouble code in the Powertrain Control Module (PCM).
Is it flashing while driving?
Try a Self Test for Diagnostic Trouble Codes (DTC)s by my pal, BroncoJoe19 @ Code Reader

No codes;
171495



ASAP, find out if speed control recall work, if equipped was completed @ Recalls Look-up by VIN (Vehicle Identification Number); or @ Welcome to Ford Owner | Official Ford Owner Site; have VIN ready. While there, see most Ford dealer maintenance/repairs done @ any dealership nation-wide.
"Summary: ON CERTAIN PICKUP TRUCKS, PASSENGER VEHICLES, SPORT UTILITY VEHICLES, AND MOTOR HOMES CHASSIS, THE SPEED CONTROL DEACTIVATION SWITCH MAY, UNDER CERTAIN CONDITIONS, LEAK INTERNALLY AND THEN OVERHEAT, SMOKE, OR BURN. THIS COULD RESULT IN AN UNDERHOOD FIRE."
See this guide by jowens1126 to confirm recall status @ 93 & 94-96 Cruise Control Recalls Repair
Note that the 93 recall is different than 94-96.

Truck is 5.0l V8,
3" lift with 33" NIttos
Transmission was rebuilt prior to my owning but she shifts smooth

My other car is a Scat Pack charger which is a beast, but I have had a few trucks (Tahoe, Ram) and never seen a SLUG like this

Thanks for the help

that will lead to some doginess, especially if it is a stock motor. but it should not be as bad as you are describing.

any codes? does it run smooth? again, run it starting in first and manually shift up through the gears, make sure you get 4 shift changes. What RPM is it at at 65MPH? should be around 2200 or so unless you are into the gas all the way, in which case it should kick it back down to 3rd.

Like stated above, check timing, set it at 10-12 degrees. Check spark plugs, filters, etc.... all the basic tune up stuff.

But a 5.0 on 33’s with 3.54 gears isn’t gonna be fast..... My 5.0 f150, back when it was an auto with the original motor, had a hard time getting to the top of the speedo(85) with 33’s and 4.10’s.....

Over time I've taken the measures below to give my '91 351 more power. All of which gave me significant power gains:

  • Advanced 12 degrees (make sure plugs and cap are newish and all firing)
  • Replaced clogged catalytic converter (this made a huge difference)
  • The gas peddle was actually bottoming out on the floor mat.. which didn't allow wide open throttle. Throttle cable is too long. I wonder how many owners are having this issue and don't even know it.
  • 4.56 gears with my 33" tires. While 3.55 with 33" and 302 is not a good combination for power, you should be able to get up to highway speeds fine. 4.10 or 4.56 gears would definitely make a difference but only done last on the list when all other power robbing items have been addressed.

For some reason the correct length of throttle cable is very hard to find online. Probably why a lot of BKO's are having this issue. All of the aftermarket cables are too long. After exhaustive research For my '91 I found this one but this Ford parts website says it does not fit my vehicle do I didn't get it. Maybe someone here will be able to verify this. 1992-1996 Ford Throttle Cable F4TZ-9A758-L | Village Ford.. I finally gave up searching and just used a steel cable clamp to set where the peddle stops.... Removing the floor mat also helped.

Did you program the PSOM when you installed the 33" tires? Check if you have the correct setting of the PSOM if the tires came with the truck.

This right here will for sure change the tune of the truck. It's a free mod and you SHOULD do it since you have 33's on it. Your transmission will thank you for it.
