EA82 SPFI surging problem....gone!
Posted 25 January 2004 - 03:04 PM
This has been hard to chase down, but my conclusion was test all sensors and switches and go from there.
I found that my TPS switch was "out of range". Now, using the Haynes manual will mess you up here.......they say to test terminal "D"......this is the power wire, NOT the signal wire!
After getting that figured out, I tested the switch UNPLUGGED from the harness with my "Fluke" meter set to ohms.............resistance should gradually climb as the throttle is rotated..........well, it did to about halfway; then it went down! .
Replacement was in order, but let me tell you; with the A/C compessor installed, it's a .............well, its a challenge.
To save others time, here is what worked ('87 GL wagon, EA82 SPFI):
Disconnect negative battery cable
Remove alternator (this is so you can get a good grip on your long tip screwdriver)
Removed fuel inlet tube (threaded).
Removed fuel pressure regulator.
Rotate switch toward rear of engine (you will have to rotate the throttle along with it).
Lift wire harness up out of the way
Replace switch; being mindful of the O-ring......
"cleanliness is Godliness" as they say.........
Hope this is helpful..............:wave:
Many Thanks to all who posted to my previous thread on this subject and also to those who emailed me personally.............

Ouchie. Advance Online wants $341 for a new one. My God. :madder:. That's half of what I paid for the car, and I paid twice as much as I should've (never trust used cars from friends). NAPA Online doesn't have it listed.
Yep, I'll try that tune-up first. And if that doesn't cut it, I'm gonna go part hunting...

Honestly, JY is probably the way I would go as well:D. Unfortunately, all the area yards here yank engines and sell them with all the stuff attached, so it's impossible to get pieces like your TPS, or the friggin' EGR solenoid that I need!

Just tell the cashier it's a "switch", don't tell them what it does........might save a few bucks that way .
Partsman, I saw several EGR solenoids when I was at P-n-P a few weeks ago...........maybe there are a few left. If I have time to go back (I need to go back anyway, I need more bits) I'll ohm one out.....if it's good I'll pick it up for you.

If I go (Murphy's Law might have other plans), I'll take my Fluke meter to check the resistance on the solenoids.............
I will PM you if I find anything .

I really appreciate you making the effort, and if you don't find what you're looking for for yourself, let me know and maybe I can find something in our fine Pick&Pull - lotsa cars to look at!

That's why it's either go to the big "D" and pay $125, or go to P-n-P and take my chances..............
The profit margin at these bone-yards is unreal.................:temper:
At least at the dealer you get a NEW part.......

I should be there about 1-1:30pm...........
Partsman, I will keep an eye out for your item...............
Otherwise, I will be looking for another Air Mass Meter......mine is "out of range"..........

Lemme know if there are any new gems in the yard. Dont forget to check the small truck section for brats.
Thats where i found a fully loaded turbo brat. Had rollbar and brushguard, both of which i ended up with.
