For this prelude i think its a si cause it's got a h22a1 vtech but i'm only make porew up to 6g and then that's it i thought it was my ecu so i changed it out but i still got the same results.

If it is a si then where should i be red lining at and should i go back through the wiring cause i just brought this car off some kid in orlando and he put a vtech controller on it which makes me think that he was having problems with it to.

I really need some help here cause i'm lost

 

could be a lot of things.
you need it properly diagnosed
