I have 89 SE 5 speed,the problem is such,when the car was cold it worked fine,when it got to normal temps it started idleing rough and bucking when reved up to 3 grand then it would start bucking at much lower rpms and the evenually shut off,when it cooled it would start back up,now its to the point where it wont start cranks fine,fuel pump is good,checked and saw that the spark from the coil was very weak,changed it still getting a weak spark,now im wondering if its the power transister ? plugs are good as well as wires & cap & rotor. Please maxima godz lemme know what else i should check

 

broken vacum lines, fuel filter, MAF, broken grounds, EGR

 

if the spark is weak from the coil, i'd check to make sure the polarity on the coil is correct

 

maf likes to do that if its not any of the other recomended things could be your ignition module that also controls spark

 

ok the infos great fellas thanx a lot,just 1 thing im a little green whats "MAF" ?

 

MAF = Mass Air Flow sensor.

 

ok Thanx internetautomar
