Overheating exhaust, engine running erratically

You gotta Love these old VG30E/i powered beasts, raw truck DNA to the core.

Overheating exhaust, engine running erratically

Postby blondy-1960 » Sun Aug 31, 2014 3:03 pm

1992 V6 Petrol. Once car has warmed up when travelling, engine starts running erratically, jolting, exhaust overheats. Have changed spark plugs, leads, exhaust.
No problems showing on diagnostics.
Any ideas? Not happy as we are due to take on holidays in 2 weeks :(
