Hi all.
Straight to the point.
The wifey's VT has been playing up at idle, sometimes stalling. 230,000 km's has LPG/petrol
Replaced plugs & Leads, but didn't seem to help much so after some reading on here decided the symptoms were Vac related.
Purge hose is fine & decided to replace the inlet manifold gaskets (which were stuffed), glad I did that.
Ok, so now idle's much better but still has a slight miss at idle & lower revs & has no Vac leaks
Purchased ALDL cable & have tunepro, also EFILIVE, not getting any fault codes which i was hoping for to point me in the right direction.
Coils seem to arc to each other with strong spark with the leads off, coil at a time, so I don't think it's them.
It's also not a petrol system/injector issue as it does the same on LPG. pulled the plugs looking for cracks but all is well
I believe it to be electrical but there is no braking down/missing under load, it runs like a clock on both fuels, just this pesky miss down low/idle
Any idea's
Thanks
