Hi

I have a Nissan Patrol 1997 GQ TB42E on dual fuel / LPG.

Here is my list of issues
1. dle is shocking. When stopped at lights I have to choke otherwise it conks.
2. Air box filter is broken therefore car runs really bad if water gets up there and also keeps backfiring.
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.
4. Radio wont switch on any more Im assuming I will just have to replace.

I am unsure of what part number to search for the air box as I believe that this has caused damage. 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?

My husband is not help and I am really limited with time and money but I know that I have to fix the car ASAP as it has become unreliable.

Thanks for any help.
