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

actually this generation of engine DOES same small changes in the fuel map in the ecu, along with idle positions and timingg settings, and shift settings if its an auto. its in the BGB so toyota reccoments tis after work affecting engine VE.
pull the efi fuse in the engine bay. sit 10 sec for obd1 and 10 min for obd2. start car let idle 5min (auto only) put in D for 1 minute. drive at moderate throttle position (20-50%) untill 4th gear. relearn is complete. (except fine tune, which your ecu will do for up to 100 starts) BUT this will def not cause a serious problem... lol This post has been edited by stephen_lee: Aug 21, 2011 - 5:20 PM -------------------- QUOTE "And, as always, your friendship, help, and dedication to the advancement of Texas Celica dominance is GREATLY appreciated.
