    Question Running issues

    Hi All I have an 88 gq petrol/gas patrol and im having driving issues from 1000rpm to 2000rpm.
    When i accelerate in any gear accept first the car stutters and splutters. After 2000rpm it runs fine although it does seem a little restricted in power. It also refuses to start on gas and will start on petrol but seems over fueled until it is warm. I have a recond. head, new leads, plugs,coil, electronic ignition module, new gas system and fuel system. I had this issue with the old point system so i replaced it with the elctronic ignition, it has helped a little. The engine was running 25 degrees of timing when i put a timing light on it, and have since backed it off to around 20 degrees.
    Can anyone tell me what the issue maybe and is this a common issue when running duel fuel?

    From the threads that are on here regarding duel fuel on cars of a certain age, it certainly seems like a common problem....... Sorry I'm of no help as only run petrol in mine but if it was me, I'd probably take out the gas system and stick to petrol. Cost a bit more to run but less problems and better for the engine buts n bobs

    Gday Kymbo4.2, As said above, when the carby gets a bit old it can start to run poorly. Try giving it a good spray with crc, wd40, penetrene or something similar and work your way around the carby trying to free up any sticking parts or linkages making sure everything can move freely. Make sure all your vaccum lines are connected properly. Make sure your choke moves freely and isnt sticking. You may need to put a rebuild kit through it. These can be found online fairly easily:http://www.ebay.com.au/itm/FORD-MAVE...d=381494342890

    Heres a few threads thatmay help: http://www.nissanpatrol.com.au/forum...-tune-problems

    in my experience with gas on older cars you were supposed to start them on petrol then switch them to gas dont know if its the same on newer gas systems or not as far as i know it is a common prob with running dual fuel although it shouldnt be a bloke i know has his running perfect on both but he is a mechanic

    would suggest putting it in the shop and getting a good mechy to tune it.

    Get the electrics spot on, new air filter get it tuned. gas likes it advanced. Gas also kills engines. Less power, dries carby etc.
    Is it really worth putting in at the current prices, lets say $50 of gas and $50 of ULP How many Ks will you do on each??
    Then go into the country where prices are .80c plus for gas not worth putting in IMO

    ^^^^^..... When I first got my GQ, I was looking at getting it dual fuelled, decided not to partly for reasons above, also mate had dual fuel Navara, just can't get it to run right on either fuel no matter what.... Cuts out, doesn't start, etc etc........ Just not worth it, for me anyway
