Actually there are a lot of theories on EMP and newer vehicles. None proven...good for us, 'cuz that means someone has to detonate a nuke to prove it!
A few other forums out there have looked into this. And the general belief is that if SHTF tomorrow...no one knows.
I have a similar problem with my '91. Turned out to be the speedo cable, it is a loud 'whirring' noise that gets louder with MPH. Usually only when it's cold out and if truck has been sitting a while.
I removed the instrument cluster and put some lithium spray grease down the speedo shaft and...
Also a thing to look at around the rear window are the guide's for the window regulator.
At the bottom of the glass is a pressed on metal guide that is about 6" long and has a slot that the roller rides in. Look at this closely because if that is rusted [common] the regulator roller will pop out...
OK, I'm about fed up with the drips-n-puddles in the driveway..[but the rust free underbody is nice!:D ]..how do I go about tracking down a PS fluid leak?
I replaced the power Steering hose from pump to rack...but still lose fluid by about a pint a week. I've checked the fittings as best I can...
Have the same problem with my '90's speedo...when its cold out it squeals and the needle jumps around. I took the instrument cluster out and used a spray grease into the speedo cable head. Long spray and lots of it...took care of it...well until it's below -20f, then I cant blame it for acting...
Heh Heh! Kinda funny you mentioned the starter! I learned 'the hard way of course' of how much of a PITA it was as well. On my 4R it was a loose starter lead that was causing the truck to not start. I pulled the starter thinking it was a dead spot in the starter that was the issue...and found...
Just did a intake manifold pull and timing belt change on my '91 3.0.
Not all that bad of a job but still took me most of a weekend. Other than getting the exhaust manifold bolts loose it should be pretty easy. Take the heads in to have professionally cleaned and gone over.
Oh! And make sure you...
So to answer my own question. Yup! a pain in the butt to fix a bad wire! :confused:
Why would a engineer put something so important in such a stupid place?
Well either way good for another 140k.
So Face2six, was it the sensor itself or just a bed wire lead? I am in the process of doing the same thing myself, timing belt is new and installed and next on the adjenda is the int. man. Just looks to be a pain in the butt to get off.
Hello to everyone on T4R.org.
I'm new to the Toyota experiance and do have to say that my 91 4Runner is a nice truck! My previous experiance with Japanese built vehicals was a Yamaha 750 and a 88 Isuzu TrooperII, both were great vehicals.
I'm a part time off roader [not that serious about hi-pro...
