just installed this engine w less than 100k on it. Runs and idles just fine until i get down on the gas pedal in bogs down @4k as if a redline. Could it be a bad ECU?

there's what looks like a cutoff ground wire connection right above the pass. headlight but dont know if that's aftermarket or stock, could that be it?

 

auto or 5speed?

 

this is a 5spd SOHC

 

I've had a similar problem with a timing belt that slipped off by a tooth.

 

That sounds like a likely scenario. If the timing is off by 1 tooth on the cam, is that 1 tooth to the right or left (counter- or clockwise)?

 

Moved the timing by one tooth clockwise. it's beautiful now. this site kicks ***
