Hey guys, new member here so be prepared to read
I got my self an automatic vx v6 berlina and as with most vx' it's had it's minor faults but there been one that no one can work out. I noticed it the very first time I drove it, under heavy load it surges (no miss fire or anything) I knew the gearbox was on it's way out so I converted it to manual in hopes that was the problem, running all vt gear (loom and computer) Everything has been married together to get it running and has been running great since except for this problem. Keep in mind it's done it since it was auto but just couldn't notice it as the box was half dead.
Here's the things I've changed:
Egr
Valley Gaskets
o2 sensors
Maf
Leads
Plugs
DFI + Coil
Fuel pump
Fuel filter
Crank angle sensor
Knock sensors
Bashed out cat (Exhaust shop said blocked cat might be culprit)
Air filter
No vac leaks that I can tell
There's more no doubt but can't think of the rest haha I'll try my best to explain it..
Say you're driving in 2nd at 40 and punch it, It'll surge through the entire rev range.. Before most people say it's "labouring" If you punch it at 80 in 2nd, same problem. Every damn gear, mostly noticeable over 3k revs.
If you build up the revs slowly in 1st or 2nd and then boot it it's mostly fine.
I've taken it to 3 different shops and none of them can access the computer or gearbox? Also, I dunno if this has anything to do with it but the A/C or fan on it's own only blows through the windshield no matter the setting? (climate control vac operated but can' find leaks)
Aaaaaaaaany help is more then appreciated as this thing is making me wanna commit hahha
