My wagon is not well after the trip down to the Scooter Rally, & so not available for the trip till it's sorted. Currently thinking ISC valve / oxy xensor, if anyone knows about cars. The LPG played up when going there......climbing a hard climb the gas did the freezer thing on me, but it's always been shakey for hard towing even though I got an LPG guy to service it last year.
Main prob occurred on the way back when we missed a turn somewhere & ended up in downtown Surfers Paradise in all the traffic & heat. All was ok till I gave the car a bit of a rest & some air with the hood up while Shel & I snacked at a servo. Pulling away from the servo the petrol accelleration was dead. Switched over to LPG & it ran lumpy as hell......felt like the car was struggling from thereon. It hadn't had a backfire, & so the vac lines were ok. At higher revs it was ok, but still no petrol. Was on the freeway, & it might have been the corrugations in the concrete road that's by Seaworld etc etc, but it felt like it was trying to do the lpg freeze again as though it was spluttering.....not really sure if it was dodgy.....might have just been paranoia.
It got up the Range ok on LPG. Currently thinking the seldom full tank of petrol dislodged some crap from the inside of the tank & so a fuel filter is needed. LPG is a bit lumpy, but not missing (like it would if a plug lead was shot) & so am thinking oxy sensor or ISC. The car has a history of not holding any idle if it was a baking hot day......after holding the revs with the hood up it seemed to cool down whatever was heat stressed......always thought it was the elctronics of the LPG system as there's a bunch of relays & an LPG elec unit up the the top LH corner of the bay, & it's very hot there. *shrugs*
It'd been quite a trooper going there....running hard on LPG or petrol.....no probs except for the one tough climb on LPG
