Hey guys, I haven't been on here lately and the Z has been running great until the other day. The car starts and runs fine and then after you take off it seems to miss. It usually starts within a couple minutes. It does it from about 1k until about 3.8k and then, the car seems to pull normal. The car just started this. There has been no check engine light so I am not sure. I think it has something to do with a wiring harness. I was trying to check if they were tight the other day. When I got to an area around the TPS the car almost stalled out. I haven't really had time to deal with it cause the weather here has been bad. I was told by a mechanic that if the check engine light never came on, then if I ran the diagnostics myself it would give no code. Is that true? I need advice because I don't want to get charged a ton for something simple. Any ideas. I looked on TT.net and I am trying to figure out something. Thnaks and sorry for the long post!!
