1998 Honda Accord EX. Problem: Engine light on. Took the car to check the code and it came back with too many codes to count. ie P0300,P0301,P0302,P0303,P0505,and P0420. The guy was nice to tell me I had a intake leak. The engine keeps misfiring high and low on the rpms. I would like to fix it myself if can. I''m an electronic technician but not in automotive. Any suggestions anyone???

p.s. a few years ago I replace the catalytic converter and 02 sensor. Still the engine light came back on.

I fix the code problem by replacing the throttle control unit. I also recomend replacing the plugs and air filter. Thanks!
