I am hoping to gain some advice about what might be the issue with my SW20. It is a 1992 Rev2 converted with Rev3 engine.
- - Upon accelerating, the car starts to hesitate and hold power. Becomes worse on higher gears.
- If you drive at constant speed between 2000-4000 rpm and give additional throttle, it starts to go but after 0.2-0.5 sec it looks like it is hitting rpm limiter.
- Above 5500 rpm it feels normal and pulls hard.
- I think it misfires because when idling I hear little explosions from the exhaust once per 2 second or so
I am thinking about a timing issue but I am not really experienced with diagnosing problems.
I hope you are able to judge from the video what could be issue.
Thank you!
