mine is 97's batch,how to check the o2 sensor?i dun know inside it got or not.i juz service my t/b as the mech said auto choke inside this and might get tis pro.but it end up the same story.my plug juz change recenty,and there is not problem when accelerationg.i believe should not relate to the plug and cable problem la!trex92 said:
97 batch dun have O2 sensors yet so should have the fuel mixture knob that is located on the firewall in the engine compartment. Black round thing close to the TB. U cant turn the knob by ur own coz need special tool for it. No probs with acceleration does not mean no probs with plug and cable. Too old plugs or cables might not give the optimum spark for combustion hence the black smoke. But since plug is new, so check ur cables too whether too worn out. Too severe case of deterioration only u would get misfiring.kob3bryant said:
i juz contact the only car modify workshop in my town(they have laptop to tune ur car),the mech suggest me to scan my car for the problem with RM60 bucks,including tuning.but when i ask about mapping,he seems like do not understanding wat i am talking about.quite bore about that.wat do u think about that?the workshop named 4GT from kluang quite active in motor show,their show car is toyota seg with 4age and green-coloured.converted quite a lot of car lke L2,mivec and son on.trex92 said:
did u change ur ECU before? If no, then there is no point to use laptop to tune car coz ur ori ECU is non programmable wan. Also if the mechanic does not know wat is mapping, then chances are he is just trying to make easy money off you. If u r using ori ECU too, u don need to worry about mapping coz the setting would never run off.kob3bryant said:
yes,my car is efi.i did not changed the ecu,it cost a bomb to me.the machine u mentioned is for tuning the air-fuel mixture rite?so wat about a light that put in front and a sensor in the rear muffler?wat is that?i kinda dissapppoint alreay,might changed the filter to the original box type.trex92 said:
as long as there is a sensor to the rear muffler, its CO tuning (tuned by air fuel mixture). And the strobe light thing is actually the timing light to tune the ignition timing...kob3bryant said:
hi, i dun understand what u mean by petrol overflow at injector o/p (o/p = ?? ). Also by car can't ignite, please give more information. Perhaps u can share info on what mods has been done on the car, type of car, symptoms of problems....v6tt909 said:
