Problems on a 91 crx............

So i just recently bought a this crx from my bud, inwhich he bought it a few years back ripped up the tranny and it set in his garage for a year or so.............. well i bought it from him for 200 bucks threw a new tranny clutch pressure plates etc in...... very cleans.......... but it has one problem runs okay i would say for about 20 minutes but then it starts to bogg down horribly.........i changed all the fluids but have yet to investigate beyond that....... i did notice that its running without a cat. converter..... straight pipe.........could that be the problem..... not enough back pressure. messing with o2 sensor? and suggestions would be helpful............thanks!

Okay well ihavemore question my ecu is throwin out 2o which is the electric load.but im not sure as to if thats orrect i havent reset the ecu since ie ownedthe car....... but would this cause a bogging down effect if the electri load was a problem, or as i posted before would the fact i have no cat. converter be the problemmaybe throwin of my sensors..plz help!!!!!!!!

Is the gas in it still a year or so old? Reset the ECU and see if that code pops up again.

no i ran it all the way down till ben using preium n it...........im open for suggestions

dont waste ur money on premium fuel.urcar is not made to run on that high of octane.it wont burn it all.

Test your fuel pump, make sure its putting out correct pressure. Maybe give it a basic tune up, new plugs, fuel filter, cap rotor, etc. If the car has been sitting for awhile, it could probably use some help.

ELD is nothing major. Mabye the radio is wired up wrong, etc.
