story:
I have a 1995 honda civic dx 5 speed trans, i'm sure it has a p06 ecu (stock) obd1. the engine was swapped out with a d15b vtec. it doesnt have the solenoid installed. I went and got emissions and failed misserably. took it to a shop and they said it was running lean... obviously since i failed on my hydrocarbons and the other one (forget name).

what i've done:
i've replaced the entire exhaust. starting at headers all the way to muffler. yes i'm including catalytic.
i've replaced plugs and wires and cap and rotor. not the cheap either.
had the injectors cleaned.

I'm running out of options because i've pretty much covered all the issues that involve hydrocarbons. the car runs beautiful except for the occasional sputter. check engine lite is on. the only thing i can think of next would be either the o2 sensor and/or the ecu. which ecu would be the best to install with this engine. please help.. i've driven myself mad with this ordeal.

thanks to anyone that can help.. it would be much appreciated

I heard that happens. it's not a vtec computer and i have the vtec engine after swap. would that throw codes and cause a lean burn?
