Ka24de misfiring?

[billy_spdips]

Yes i have went threw many different threads on this issue but no answers. Ok so I have an s13 ka24de and the car is misfiring.while attempting to drive it it struggles to go over 2-2500k. And it does go into limp mode when I unplug the MAF. The only code it's throwing is 12(MAF). So far I've replaced the MAF with a said to b good one( cleaner then my old one) replaced the coolant temp sensor(to clear that code)and it has an egr block off plate. Any info on this would b awsome

Whats your ignition system look like? Base timing set?

check your timing and your fuel pressure/ pump. have you checked the tps? let the car run and unplug it if it doesnt change then theres your problem. its the sensor on the throttle body. 50 dollars at your local parts store.
