Hey guys, I just changed out my head gasket not too long ago. After everything was put back together I drove it around a bit and the ride was good as I expected. But a few days after I tried to just floor it to see what it would sound like(just got my exhaust done 2.5" catback and custom intake). Yeah it sounded really nice but I noticed the more the RPM rose the more power was loss, but the engine got louder at 4500RPM and it reminded me of the VTEC that Honda has. I know its a 5SFE and they are like boat anchors, but it sounds to me that my timing may be off. Heres a video of what I was trying to describe, sorry for the poor quality it was hard to try to record, steer, and shift at the same time kindasad.gif

Update:

I changed my alternator( it was garbage), spark plug wires( they had a few rips) and cleaned off the spark plugs. It runs alot better and I have no more misfires. However, I'm still having that struggle in the higher rpms. I'm going to check the timing tomorrow with the light and I'll go from there.

Good to know that helped. If timing isn't your issue I suggest taking another look at your sensors(IAT,EGR,O2) because it sounds like your having troubles with proper fueling.

Stephen_Lee Im sure you know this but to clearify on your post about BGB, that will only help if those sensors and sending units are properly working and thats the main point Im trying to get across and i guess i could have done a better job about it. frown.gif Thats why i try to steer people from just sitting there and pulling fuses and trying to reset programs, its not going to help if the ECU isn't even getting the right signals.

Yeah, I agree with you totally. The point I was making in the first post (I said it at the end of it I believe) is this is the proper way to do it, and yes it helps but only AFTER certain types of work has been done to the engine. In his case I don't believe it would've helped.
