i try to look but cant find. so please dont get on me. i got b18b1 turbo. i had a fuel injector code 16. so i ran some sea foam and it cleared it. so i thought it was the problem why i couldnt rev but then i took it out and it wont rev pass 5000rpm. i already mess with my main relay also. i re-soldier it but sometimes my car wont start and i have to hit it. could it be that? also i check the timing and dizzy on it and its fine. didint check the fuel filter yet but dont think thats the problem. could be fuel pump? or could it be a bent valve?
