Power Questions

[ajward]

Perhaps worded a bit awkwardly, but a couple of engine related questions.

My truck: 1991 Ranger long bed regular cab, 4.0 V6, A4LD transmission, Limited slip axle (don't remember which, at the moment)

First: In the morning, the truck seems to bog down momentarily when I step on the accelerator. Maybe like it's not getting fuel. After the engine warms up, this goes away. Didn't used to do this. Is this serious. Do I need to panic?

Second: When it's been raining, I'm kind of hesitant to drive my Ranger, because the back end wants to go all over the place if I try to accelerate more than just creeping along. I know pickup trucks are light in the rear end, but this seems a bit excessive. Again, is this normal? (Tires are in decent shape)

Thanks for any input,

Amanda

I'll try

First problem could be the temp sensor that sends temp to the computer. It might be telling the computer the engine is already warm when it is actually cold..

Second problem. I'm betting on a LOCKER in the rear and not a posi traction. You describe a locked rearend on wet streets. A positraction allows one tire to spin a little and shouldn't do that on a simple wet street.

Hey Big Jim...

Thanks for the reply!!

That sounds reasonable... Is the temp sensor a huge fix or maybe a shade tree repair.

Lastly, I haven't physically looked at the axle, just took the axle code from the door sticker. It indicates a code of D5 and, from my research, seems to be a 3.55 LS differential. I took "LS" to mean Limited Slip... am I wrong? (Often, I am )
I'll crawl under tomorrow and see what the axle tag says.

Thanks again...
