when i checked the timing of my 93 na auto, its like more than 30 degrees at idle.. i changed it back to 10 degrees but now it runs sluggish, not the same power it had before i corrected the timing.. anything i need to check? crankshaft and cam gears are in sync when i rotate the crank to TDC the cam gears also align with the timing marks on the cover..
its like...
10 degrees btdc = poor performance
more than 30 degrees btdc = good power, runs ok
this is kinda odd.. i just want everything to be within spec.
checked valve clearance and its still within specs. tps adjusted correctly
