misfire after new timing belt installed?

SMARTY PANTS!!! Take $20 to your local quicky lube, and ASK them to clean your THROTTLE BODY and IAC valve. That is the IDLE AIR CONTROL valve. The IAC is the HEART of your fuel mixture, idling and fuel mixture CONTROL. It accepts signals genrated by your O2 sensors and fine tune the mix!!! Your check engine system is TELLING your that your fuel mixture is going south, OR that you are using IMPROPER engine oil in your engine. Only engine oil that has the name HONDA on it should EVER be used. NO BULK oils soming from the ceiling of the jiffy lubes. Your engine will simply NOT work it's BEST without synthetic engine oil, like MOBIL ONE 0W-30. Go to the HONDA dealer if you have to but GET THE T. BODY and IAC cleaned up to SHOWROOM clean. Otherwise you risk converter and O2 premature failures or severe clogging up. IF this does NOT help, GET TO THE HONDA DEALER before something EXPENSIVE breaks for you!!! WHO did the timing belt??? Only GENUIN HONDA coolant can be used in your engine, and NOTHING less! there are LOTS of uninformed mechanics out there that really know NOTHING about the consequences of their material choices and OTHER things on down the ROAD!!! AUTO ZONE free OBDII tests will point you in the RIGHT direction. LOTS of info, hope you get it all!!

You have the potential for a real problem here. It's possible that when the belt was changed the valves got out of whack with the engine. that's bad juju. Or it could be something as simple as connections left unplugged. check for unhooked wires. If you can't find any have the car towed to the shop. The traction light being on makes me think the latter is more likely. it sounds like a computer issue, but DON'T find out the hard way that the engine is out of time with itself. get it to a shop asap if you can't get the issue fixed yourself.
