i am currently running on 5w30 i have been warned to used that grade of
motor oil if i dont want any problem with the valve lifters witch are
prone to stick on high milage car ( my car has around 122000 miles on
speedo now) and when the lifters stick the exhaust valve burns :(
so i am more carefull about motor oil now
by the way today my problem got worst i was comming back to home when
my car gradualy lost power it hapen 3 times before i was home on a 20
mile trip on a rainy and cold day with the heater fan on at slow speed
when it happed the first time the engine stall then restarted and
everything was back to normal until 5 min later the same thing happen
but no stall this time then again the car engine suddently came back to
normal now that it is worst it will be easyer to troubleshoot the
problem witch i think is a bad electrical contact on a connector
somewhere on the car or a bad efi relay or the ECU/ECM itself
