Hey, I have an '85 bronco II, Has a new 2.8L, with about 20,000 miles on it and an A4LD autotrans. The trans has about 15,000 on it. drivetrain is all stock except for a 4" rough country lift and 31" Cooper sst tires. Motor has headers and a 2 1/2 inch exhaust, no cat. Having problems with hesitation on the motor and to boot it is intermittent. Some times the truck has no hesitation, put the pedal down and it takes right off with no problems pulling, other times it is horrible and just bogs. You then literaly need to mash the pedal to the floor to get any rpms on the motor but it quickly upshifts and bogs again. Any ideas...we were thinking that it ultimately was the carb. looking at swapping in a holley 350 cfm 2 barrel. Holley has a throttle position switch and auto choke conversion that will work for this application. Has anyone done this or tried it?
The other issue is the trans, when cruising at 45 to 55 mph, it constantly goes in and out of overdrive, constantly up and down...gets annoying. Someone told me it sounds like the throttlr position sensor, anyone have any suggestions?
I love the truck, drive it everyday, the steering it horrible and scary at times but I think that is just the cheap rough country lift, I plan on putting in a james duff 5 1/2 inch stage 3 lift with superlift superrunner steering system this spring.
Thanks everyone
