my toyota 4runner drives like a kangaroo
Hi Im David from Ireland,
I have recently purchased a 1994 Toyota 4Runner, 3Litre V6 petrol, manual with 106,000 miles on her. It is is LPG/Gas converted.
Here is the problem- I put on a K&N air filter, and all was goin well until one day as it was running out of LPG it started to chugg- this was normal(when this happens you just switch to petrol) but this time as i was switching across, it back fired and blew the air filter off along with the air flow meter and the car stalled and would not start again untill I screwed the air filter back on again. but then as I drove it after it started chugging and driving like a kangaroo, especially in 4th and 5th gear. It has been doing this ever since, the engine used to idle at 1,500rpm but now it idles at 500rpm, sometimes it starts fine(idling at 1,500rpm) and drives fine then it starts to go funny again and kangaroo. and when i switch it to LPG it still drives funny and when i clutch it on LPG, the revs drope right down and it stalls. I have since put the original air filter system back on but the problem remains.
Is it possible the engine was damaged when the air filter/meter blew off? Or do yous have any idea? I know that LPG connverted cars is not a common thing, and I certainly dont have clue about them!
Thanks a million, David McFarland

I have run into something similar on boom lifts I work on that are LPG/ gas powered. It sound like it may be trying to run on both fuels now. Try running it on LPG with the fuel pump fuse pulled out. If it runs better the solenoid that switched between LPG and gas may be stuck or bad. If this is not the problem it was a cheap and easy check and you have eliminated one possible variable.

I have this same problem with my 94' 4runner. It is a 5-speed and it starts fine at about 1200-1500 rpms but as soon as the engine starts to warm up they drop slowly until its only about 300-500 rpms. If I let it idle too long it will die when the engine is warm. With the clutch in it idles higher then with it out, is that normal?

Sorry, but he is the only other person on this board that i've seen with the same problem. I have posted a thread before and got little response. If it makes any difference I also have a k&n air filter installed.

where ever you took your vehicle to get certified/saftied, should be able to point you in the right direction. someone had to install the lpg system, look in your local directory for lpg conversions etc then start making phone calls.
