Hello,
I'm a new 'vette owner since 8/06. I've got an '84 Crossfire that has continued rough idle issues. I know, I know! Why did he buy a crossfire??? well, I believe that it's still a great car! Anyway, I've done so much to try and improve this idle. I had it professionally tuned at a Corvette shop using all new Delco parts; New wires,plugs, cap and rotor, pcv, fuel filter,ECM,TPS,MAP sensor, EGR, and last but not least, a new GM harmonic balancer as they told me it was spun. Now, it runs just a bit better (at least it doesn't cut off several times after starting like before) But, it still "chugs" along at cold idle and only slightly improves when warm. A few vacuum lines were also replaced with no resulting improvement. They told me "this crossfire will always run rough" ( which I don't believe that it should). After warm up when I hit the gas when driving, it does not respond well until I "step on it". I use 93 fuel and try to run it enough to get some new gas through the system. What else am I missing here?? HELP! Is it more vacuum leaks at certain areas? Any help would be appreciated.
