I'm having problems with my KA24DE and was looking for some help. Any info or thoughts you have on this problem would be much appreciated. I have searched and have found lots of useful info but nothing that quite answers my question.
I currently drive a 1996 240sx with the original high mileage KA.
My car keeps cutting out while driving. It feels like it's not getting fuel when this happens. It happens after the car is pretty warm, about 30 to 40 minutes into the drive. I'll be driving and all of a sudden nothing. I hit the gas and nothing. Well sometimes nothing and sometimes it will rev to 2500 RPM but will not go above. This happens for about 1-2 seconds sometimes 3-5 times in a row. It did it once when accelerating from a light today and chirped the tires twice in front of a cop.
It goes away but comes back often. I took it to the mechanic but they just keep saying it has to get worse to figure out the problem.
It's getting annoying and kind of dangerous when I cuts out at highway speed, someone almost rear ended me today.
I have a obd scanner but it's not very good. I got some error codes but no description of what they mean:
P010
P040
P013
P144
My KA has some of the emissions stuff removed/blocked off so I am sure that is some of the codes it is throwing.
I have had some friends guess at it.. Bad injector, MAFS, fuel pump, distributer ect. but don't want to just guess and throw money at it.
If it is an injector or the fuel pump how can I check that? It never does it at idle. I did a tune up and replaced the plugs, cap, rotor, fuel filter. All the normal stuff.
