Engine light has turned on
My 2007 jeep cvt 2.4L benzine was converted half year ago to work on CNG natural compressed gas.
anyway 2 weeks ago after I have contacted the NGK spark plugs company inn the US, they advised me to switch to a different number of spark plugs, instead of the ZFR5F-11, to buy one degree colder which is ZFR6F-11
after I bough last week, car worked and between time to time made some gaps though it feels better with the strength of engine and burning way, but I recently got my engine light on, I guess its because of it. so I removed the plugs and put the old ones, removed the positive battery connector for 10 min, then driven the car for a while then turned of the engine, again turned on the error disappeared,
yesterday was driving and almost after 40 km the error light started again, now I don't know what to do? any advice please? should i use these error code reseters, or some other advice?
our dealer in Finland is a money sucker, so would charge me alot for anything.
any advices are appreciated
