VS Ute possible head gasket?

[Wozza]

neg battery term off, remove the plugs on the tps and IAS inspect for damage and spray with some contact cleaner...check there is no vacuum hose in that area that is perished and moving with the harness....make sure harness is supported and has sufficient slack in it, fix the earth wire with a more robust one...check engine mounts are fine (maybe pulling on harness when motor moves)As you had to mucked around with the T/B area when doing inlet it may just be a loose connection and not related to the shudder...Also as you have digested coolant through the motor the O2 sensors maybe stuffed and the plugs may need a good clean/going over....

Hey, just did the valley gasket and it was pooped as hell, saying so it has not fixed the studder at all. I wiggle some wiring (near the T/B) such as the tps and idle sensors and the motor starts to rev up and down accordingly to the way u touch it (lifting it up and down) i did notice there is a skinny black earth on the back of the motor passanger side that looks a bit how ya going and the temp signal wire (on thermo housing) is allso how ya going and does the same as i said above.
Any ideas? Or can you point me some where with common vs wiring issuse.
Thanks!
