Hi stop start tech uses a different battery and wiring plus normally 0-20W OIL SPEC plus ecu and clutch switch , i would imagine it could be done with a few upgrades , some one like motec for ecu if they do one , not sure on additional sensors though ! but would be expensive !!!

Known fixes on autodata for gs are front anti roll bar bolts come loose or need loosening and re tightening it shows all bolts associated with the front roll bar set up .

Hi Yes thats right modified piston and rings big end shells should be fitted as long as you have s/h u should be fine . traditionally though your symptons would point to valve stem oil seals , but these would be changed anyway with the modified rings etc as they would generally de-choke the valve train .

Hi Can anyone recommend a supplier of oem stereo lcd display , as mine is faulty on my 99 GS not navigation , or recommend a repairer many thanx.

Hi im a toyota technician, juddr through the steering wheel when braking is generally warped discs, a skim should sort, most dealers have the equipement to do this but may take a few hours to do properly , in extreme cases the cause can be warped hubs u can determine this with the use of a dti guage set on the disc face rotate disc 360 and make a note of the highiest point on the guage mark the dics at that point with tyre chalk (yellow crayon) , then remove discs from hub and rotate as close to 180 as poss hard with five studded hubs , then set up and measure again if chalk on discs matches as before its discs if not its a hub/bearing problem.

Hi Mike, the concerns with engine lights coming on were the first signs of the valve clearence issue but we didnt know it at the time the car seemed to run ok but after the valve adjustment the fault did not re occur for quite some time but would reoccur due to the engine not having hardened valve seats maybe its worth doing some investigation as to weather your car has or has not, the kit your man fitted is designed to combat this , as for valves burning out misfire could occur , harder to start from cold and eventually loss of compression , wet or dry test would return the same compression result pointing to a valve train fault and not the piston rings , hope this helps and good luck in finding the cause . PS Is the engine fault code related to the hegos (heated exhaust gas oxygen sensors). toyota refer to oxygen sensora as air flow sensors not to be mistaken with maf or map sensors.

Hi Mike, Was browsing the web last night and stumbled across your thread whilst trying to locate myself a gs300 mk1 , i am a technician and former mitsubishi senior tech , have had some expirence with lpg whilst at mitsubishi way back, we had some concerns with dtc`s being stored various software rewrites were released to no avail , in the end it turned out to be to do with the engines valve seats , which required the valve clearences to be corrected , this was causing the hegos to register faults , im not sure if your car has hardened valve seats or not but some mitsubishi`s didnt , i previously worked with a polish technician at toyota , in poland lpg is very common and he said valve seat were a big problem, adjustment was carried out on most services on toyotas where applicable , we have had some security (high mileage) vehicle fitted with lpg which have burnt out the valves , if the clearence is to tight the valve over heats as the valve seat cools the valve through convection , when it is shut if its to tight the valve does not seat properly and cool enough eventually leading to a burnt valve, hope this is food for thought.
