After performing the running test, I get the following codes:
136
536
521
553
652

YIKES! Check Engine light is going on and off while driving or idle; with no rhyme or reason.

Your help is greatly appreciated!!!

No, it doesn't help. I have the book that tells me what the codes mean, now I need to know what to repair. Even moreso; where the heck do I start???

136 - HEGO sensor indicates lean condition cylinder bank no. 2

536 - BOO switch circuit fault/not activated during KOER test

521 - PSPS circuit does not change states during self test

553 - Air management no. 2 circuit Fault

652 - Torque converter clutch solenoid circuit fault

TX!

Does the car run? Symptoms? Warning lights on the dashboard? Tell us about your car. How many miles? You are not going to leave your car at a shop without telling what's wrong. Same here. Maintenance done recently? Like spark plugs and filters?

Check engine light comes on intermittently; after car seems to get warm it looses power; 100K on this engine. Seems to run OK, just a little rough at times. Starts right up though!
