I have a t-maxx 2.5 that i recently put the new 3.3 engine in and just broke in the motor. Soon after the break in, the engine would only run for a bit when it was cold and then dies soon after i started running it hard. So i thought it was just the glow plug. But I was wrong because every time i put a new plug in, it doesn't do anything different. Now the engine hardly idles and is a pain in the butt to even start. What should I do. I tried tunning it and it just doesn't seem to do anything either. HELP???
