It ran great when i got it. Then it started with the hesitation. Its almost like i let my foot off of the pedal. It had 83,000 miles on it when i got it. So i replaced fuel filter since i was under it went ahead and put fuel pump on. That didn't work so i changed cam and crank sensors. Didn't help. I started getting a code for throttle sensor. So i ordered a throttle body from needswing.Ran fine for a few weeks. but started getting multiple misfires. Checked my coil packs 5 of the 6 were cracked. Thats when i did the tune up. I was having problems with my navigator vacuum lines so i replace all of them on the crossfire to. Today i pulled the air box off trying to find a leak. Noticed the mass air flow clip wasn't tight. The elbow was just moving around. Had to put a zip tie on it to tighten it. So far it hasn't hesitated. Love this car but its being difficult.
