Today I replaced my spark plugs, took my throttle body off and cleaned it along with the egr valve, tps and maf sensor. The egr valve ports were completely plug off. The valve wasn't working so we cleaned everything hot it working. Put everything back together and now it hesitates to throttle up and when on gear doesn't get any power. The codes it's tripping r 0743 and 0755. One is torque converter clutch solenoid and the other is solenoid b not working. Was there something around the throttle body I could have loosened, broke or whatever to cause all this or is it just possible it just so happened to go bad as I did all this. Haven't had any issues with vehicle other than it running a little rough before I cleaned and replace everything.
