Loads of Issues

[YNOT]

1. Idle is shocking. When stopped at lights I have to choke otherwise it conks. This could be either fuel or ignition related. Does it do the same thing running on LPG and petrol? If it's the same on both fuels then it is most likely caused by ignition.

2. Air box filter is broken therefore car runs really bad if water gets up there and also keeps backfiring. A broken airbox is unlikely to cause it to run rough and backfire in wet weather, that sounds more like water getting into the ignition, specifically the distributor cap.

3. Hard to start have to crank like for a minute for it to start usually have to switch back to fuel. Can often smell gas when starting. Does it start OK on petrol? I suspect the gas system may need retuning and possibly also need LPG converter or mixer (depending on type of LPG components fitted) rebuild.
4. Radio wont switch on any more Im assuming I will just have to replace. You may be able to get the original radio repaired, but why bother, cheaper and easier to just buy and install a new radio/CD.

I am unsure of what part number to search for the air box as I believe that this has caused damage. I doubt the airbox has caused damage, more likely the airbox was damaged by the back firing caused by faulty ignition or poor LPG tuning.

Also I think the spark plugs might need replacing - please correct me if I am wrong. Just take forever to start or do you think it is the leads? I realize you say you have limited money but I think you're going to have to throw a bit of money at the car to fix these faults. I would start with a new rotar button, distributor cap, plug leads and spark plugs. Get the ignition timing checked also. That should take care of the ignition so you only have to get the fuel systems right.

One trouble with dual fuel cars that run most of the time on LPG is that the petrol system deteriorates from lack of use. The petrol goes stale in the tank, fuel pumps gum up and seize up, injectors get a carbon build up on the tips etc etc.
