Looked for Tip 5 today.

messuring from TPS ground wire to batery negativ is 2.6 ohm, from TPS wire to the spot at the block where they are bolted on I got 0 ohm resistance. from battery negativ to the spot the battery cable is bolted on I got 2.6 ohm resistance.

I do not know why there is resistance when I bolt the cable to the block but not when I messured the engine wiring itself or the cable from the battery to the block ??? when I put the cables directly to the battery ground there is no resistance between the TPS and the battery negative ground, as it should be...can I bolt the wires directly like this or not?

Tip 6 cures what you are finding in Tip 5.

It did not cure the problem. I did everything.

I have no resistance in the engine side of the wiring. No poor grounds, added new cables.

The only resistance comes when I plug down the battery cable to the block.

I also searched for the brown cable. It went from TPS another from IAT and from MAP to the firewall. Then to the left side. There is a crimp where they went into one. This goes on the left side of the block but where? The dipstick cables are different black ones...

Eliminate those crimps by soldering.

Soldering is what i wanted to do but I can not find the other side of the lonely wire. There is no connection near the map as you wrote in your Tip 6?!?

I can take a picture so you can see it. I also built a wire from battery- to the dipstick bolt. When I take off all cables from there directly bolted to that cable 0.00 ohm. When I put all of them to the block I got 2.6 ohm

Lonely wire?

yes I mean that single one that comes from the crimp

Eliminate the crimp and solder it.
