Hi Guys...
Whilst the car's due out on the 4th of July for the new engine, I figured I may as well spend some time resolving issues that have been plaguing me for a week or two.
During the "rev" range, the car's tacho goes WILD and it behaves like a tempermental three year old between 600-900 rpm and 1350-1850rpm. It's also starting to show signs of it between 2300-2600rpm.
Basically it misses over these revs, misses, backfires, lurches, jolts... you name it, it's really annoying and has almost gotten me collected at a number of intersections.
The vehicle's fitted with LPG and you can sometimes hear the backfire come out the intake instead of the exhaust. The carby was rebuilt by me and the float was set, but I imagine that this might be the problem and/or it might be out again.
I'm really really really unsure on how to tune a carby and my mechanic was instructed to fix this last time and promised me he did, but obviously hasn't. The car's got 280,000 kms on the clock... 170,000 miles or so? .. In 4 weeks or so it goes in to have the 1UZ-FE fitted to it, but I don't have my other car anymore (it's sold in the morning!) so I have nothing else to drive while this problem resolves.
Would appreciate any help at all.
I haven't done anything yet, I'll probably start with plugs, leads and points! Leads are 8000 km old so still basically new!
