whats wrong with my engine???

My car is fine for the first couple minutes i drive it, but when it gets to operating temperature it starts puttering and i have to stay in first and second gear. Basically as soon as i step into the gas a bit, it goes from a clean drive to: pop pop pop pop. It kinda seems like the fuel system is airated or somethin but I don't know if thats the case. Originally my pump was running to high, but I've got it at the right PSI now and I've done a fuel pressure test. Has anyone experienced this, or know why it might be doing this? BTW its a 98 H22 converted to OBD1. And I should mention that it was running fine for the first two weeks before it started acting up... maybe something to do with the heat and ventilation of the gas tank???

Re: whats wrong with my engine???

I fixed it :) the spark plug gap was too big... lol. Probly one of the first things I should've checked. The pressure was at 60PSI but I put a rheostat inline and turned it down to like 35 PSI. So now not only is my car driveable, but it doesn't backfire anymore and it's running better than ever
