Thanks supra_gurl, I'll check that out soon.
First off, the turbo spools up nice. I had a dummy on there after the rebuild and this one was installed when the valves were replaced. I'm only getting 5-6 # of boost, but it/s not 0.
Second...
I still have the 6 bent valves from the belt slip. the 7m IS an
interference engine. if the belt were to break while the engine is spinning, i imagine the valves would be pounded to hamburg and the pistons would be ruined. I had to re-machine the valve cutouts in the piston tops for only 2 teeth worth of belt slip. Another tooth worth and i would have replaced 12 valves, whereas the exhaust cam is set in such a way that one set openes just before the other. only reason i can see why only 6 were bent , and only just barely. but yea... find an old supra in the boneyard, remove the timing belt, then slowly turn the motor by hand. i guarantee the motor will stop abruptly.
3rd. it does throw a code when it goes to hell. code (note cobe) 41.
tps sensor circuit. I will do more testing this weekend.
thanks for the ideas... keep em comming...
Peace
Rodster

that's ya first thing you need to do, could even be knock sensor problem as that will richen fuel & retard timing something silly
if your check engine light is coming on there will be codes stored
and it is highly unlikely any valves were bent as the 7m is a non interference engine  |
