hi all sorted at last turned out to be a simple little issue after all tps sensor had bent pin in it and wasnt getting a reading which naturally was giving me no throttle response and starving my motor of fuel hence my miss sorted the sensor and now is running sweet as a nut cooling system bled out after a little more time and paitence had been applied been driving for a few days now and all seems good lots more power than before and starting hot or cold no problem a happy ending yipee thanks for your help anyone who replied especially ormi ps i bought a full workshop manual off ebay for this motor covers everything i can send it on free to anyone who wants it proved usefull t me it cover gs 300 and 430 seems to be for mk2 model :winky: B)

try tony on 0035349 5556171 hes in ireland too but bes over and back to uk in his van has hundreds of body panels and bumpers and is neighbour and freind of mine sound man dont abuse his number thanx

sounds like either a wiring fault between the pedal and the ecu or between the ecu and the throttle body or a sensor somewhere hasn't been plugged in? did you replace the spark plugs? the cooling system might not be blead right ie their could still be some air trapped in the heater matrix/or a faulty thermostat could cause problems as for the miss fire a dodgy ht lead(wrap tape round to check)or coil fault toasted valves go hand in hand running lpg as it burns hotter. have double checked everything gs430 not popular in ireland parts are scarce i didnt notice a bleed on the heater hoses ?? is there one oh and yes i have replaced and checked all spark plugs and coils and injectors and all loom plugs im lost on this one and i dont give up easy im qualified mech and see lots of problems every day was hoping to get ray of light from someone with similar problem but have searched net and no similar can you get a throttle body anywher e and does it have to be set /calibrated?? like the iuzfe

In the last week I'm having exactly the same problem with my 2003 GS430 and the battery appears fine. It wouldn't start this morning on a couple of attempts, but on the third I turned it off and went straight from off to turning the engine over, instead of waiting on On for a few seconds, and it started like normal. Where can I find the starter motor on my car to have look at it? starter is in the middle of the V of the engine not east to get at need to remove the whole inlet manifold assembly not really for the faint hearted hope your problem is the battery or the solioid not sure if its a remote solioid but i will look tomorrow and post again

hi all kevin here new to this forgive me for jumping in at the deep end but i am tearing out what little hair i have left because of a gs 430 a little history for you been on lpg since almost new ran well since 2002 till last year would start every time fine when cold but would stall as soon as you put in gear (auto box) then would be extremely slow to restart sometimes not atall till battery flat had been using a little water for a long time maybe only a pint a month or so would usually freeze the gas conversion when water was low had checked on pc before work started diagnosed a misfire so back to garage done cold compression test and results were poor 60 to 90 psi on all cyl one was down at 35 that was my missfire i guess so now to the water leak wasnt external so looked like head gasked had some small bubbles in rad pulled off both heads all valves on exhaust side were toasted on both heads got all ex valves replaced, heads pressure tested, skimmed new head set of gaskets pistons and cyl all looked fine as you would expect for a 90000 mile motor happy days the heads were ready for back on replaced t-belt aswell lots spent by now as you might have guessed Now for the bad bit turned the key and guess what still had missfire and next to know throttle response max 2000rpm checked compression again all ok 140 to 150 psi checked spark all ok throttle flap not moving in response to pedal movement back to computer cleared all faults except one throttle posistion sensor wouldnt clear ut i dont think that will cause a miss????????????? just to put the tin hat on it im not right convinced the head gasket problem is sorted either still runs hotish rad hoses are faily hard but no bubbles in rad has any one got a reason why i still have a miss and why my throttle sensor might have died help plese this car is driving me stray
