The engine is a OBDIIA B18C1 and about 3 weeks ago I was racing a friend and I accidently hit the rev-limiter then when I switched gears I wasn't able to rev past 5500 rpm and the tach just bounces there but if I turned the car off and back on, problem solved.

This has happened a few times since then. At first I thought it was the ecu causing this because when I turned to car off and back on it worked fine, But last night I was racing another person from a dig and I was shifting at around 7200rpm and the car felt kind of sluggish, which I didn't even realize untill I hit forth gear and I felt alot more power come to it.

Then when we tried to do a run from a dig same problem it wouldn't rev past 5.5k so I shut the car off while driving and tried to start it again like I had done 3 or 4 times before this time it wouldn't start and I couldn't tell if it was turning over or not. So now im kinda thinking its the dizzy, any ideas?
