Spare part, won't go into overdrive..

[brentusbrutus]

I changed my 3 rear universal joints in my 84 Bronco. Whew..what a horrible job that was.

When I finally reattached my rear drive shaft, I noticed a piece of hose lying on the ground. I figured it was just a piece of old gas line that I had had changed out awhile ago.

I took it for a test drive, and my baby ran like the wind. Two days later, I put my trailer hitch back on, and rented a garden tiller. After I returned it, I noticed that my motor would bog right down when I tromped on my gas (tryin to race a chev).

What gives? Could that "old gas line" piece be part of a transmission vacuum?

What are yer thoughts?

The vacuum line to the transmission usually connects to a steel tube that runs from the back of the engine to the modulator on the transmission. The hose you found could be the vent to the transfer case. Bogging can be a lot of things from the transmission kick down to fuel supply. What year truck and engine is this?

HI..

84 BRONCO, 302 (FROM A 1972 tORINO)

Oh sorry I see you mentioned the year in the original post. Any way, then you have a carborated 302 and C6 transmission right? So kick down is handled by a rod from the carb linkage to the C6. Check the connection at the transmission, sometimes the C clip comes off allowing the rod to become disconnected.

Other possibilities are timing and vacuum advance or carb problems like the accelerator pump or power valve.

Good luck,

Thanks Seabronc..

I will be looking into your suggetions..

It was stupidly hot as well when this happened the other day. Could the weather be a consideration? It was 33 degrees celcius. I know my temperature gauge wasn't abnormal..

I suppose it may be a factor, especially if that is the only time it seems to happens.

Make sure all your vacuum hoses are attached securely and that they're not plugged up!

Check your vacuum advance module to make sure it's working correctly.

Thanks Colleen..

I went out for a nice but risky trail ride by myself the other night..(scared a rabbit !!) and when I got out to the main road again, I stepped on the gas, and the same thing happened again. I popped the hood when I got home, and I noticed my PVC Valve hose was kind of crushed. THe hose was sucking in on itself. I was going to change that hose with a stiffer hose to see if that makes a difference..

Do you think i',m on the right track..

I think you're on the right track there. While you're at it..check all your other hoses...what kind of heat have you been dealing with???

28 to 33 Degree Celcius

quite warm..

But I think I used fuel line whan I changed out my PVC Vent Last time. I need to fine the correct stiffness of hose.

Sometimes when you have it running you can hear the vacuum leaks.
