Thread: Need help?????

Having a problem which I can't figure out. Car start good with a jump start and have an Aem ems 2. Ok here's the problem, on my cluster the car is over heating wit the fan on direct but on my ems, coolant sensor read 108 109. Doesn't go any higher and the voltage on the ems is stuck on 14v's no lower or higher...Soo wat might be wrong if any one can help me.. Also won't rev pass 3500 rpm due to Maf to map sensor change and when I rev a few times, the car get stuck on high idle and I would have to plug out a vacuum to have the car rev down to about 1000rpm. Engine is an sr20ve-t wit adjustable cams, sr20vet metal head gasket, 750cc Injectors, plus more. Need help ASAP.. Any advice is appreciated....
