silvertop or blacktop ?

i'm guessing it's a silvertop...

 

[plank]

it's black top..
is that symptom of defect fuel regulator.. or fuel filter clog..

 

[chinozie]

so many possibilities...
firing system, fueling system...ECU maybe...
need to narrow down the problem...

try to diagnose it first...

try this first :
Diagnostic Codes

problem solve in magic way..
only disconnect battery terminal for few second,, then reconnect battery terminal.. start engine problem solve,, idling speed normal...
i don't know how to say.. only easy method can solve this problem,..

 

[Dayline668]

Magic..? dun think so.. better go check up..

 

[chinozie]

have you run the diagnosis before plug the battery terminal ?

 

[plank]

tomorrow do that diagnos,, may be this 1st sign for defect,,,

Probably should be ECU & MAP/AFM problem.
