i search but no answer. i got a built h22a4 and got it tune 2 days ago. everything was running fine until yesterday afternoon. took it out to the store and it ran like ****. start to bog and then feel like im only running on 2 cylinder then i die. took a long as crank just to start it and it idle around 200-500 rpm. got home and change the msd coil and it ran normal. shut the car off let it sit for about 30min and start it back up and it die after a minute idle and now it wont start at all. i check all sensor, ground, wires, gas, and sparks. everything is good but it got a very low sparks on all 4 spark plug wires. i swap the msd kit back to the stock coil and rotor and nothing at all either. if any body knows anything about my problem please let me know. thanks

 

What about your plugs and wires? Are they good?

 

Did you check the timing?

 

Or it can be as simple as a loose ground wire.

 

All plugs and wires are plug in and good. All ground wires are intact.
