Check the ground on your maf.. The ground will run from the maf to somewhere on the intake manifold. It should read no more than .09v If it reads more than this you need to reground the MAF. This could be one of your problems.. List your mods and ill try and help you out as much as possible. The other thing that it could is your Temp Sensor for your ECU.. there are 2 temp sensors one has a single wire going to it.. this one is the temp sender for your temp gauge on your dash.. the other one that usually has a Red connector (and it has 2 wires) is for your ecu. My friend just had the same problem on his FWD sr20de+t and i replaced his temp sensor (ECU) and it runs like a champ. I also replaced the connector.. Try this two things out. Hopefully this helped..
