New timing belt questions

I recently purchased an 06 wrx with 82000 miles, the dealer put on a new timing belt, two coil packs and a water pump, on the way home on the highway I downshifted to fourth to pass someone and around 4k it bucked and CEL turned on.. Anyone have any ideas on why this happend!?!

you need to have the code checked to find out that the light is on for. Then have someone test test/ check whatever component or system the light is on for. the CEL can come on for hundreds of different things.

I would still take it to a dealer and see if they can pull any history codes out of the ecm. There is no telling what it came on for without looking, and no way to give you any sort of answer either. Any number of things could set the light off under those conditions

Doesn't mean the code is gone.

There are many ways to check for CEL codes, including the Dealer option mentioned above.

There are hand-held devices available at auto parts stores, there are engine tuning devices like the popular COBB AP, and there are big $ diagnostic devices at auto shops.

It might give you some peace of mind if you find out what the code was, if you also get some indication of whether it may reoccur again at the same time.

I'd find a competent mechanic familiar with Subaru performance cars and get them to check it out. You might need maintenance services later, so it'll be of future benefit too.

I believe that is a wastegate control code or too high boost pressure or something like that. Cobbs website has some simple explanations of it.

That's an overboost code. Do you have any mod on the car. You might wanna check your wastegate arm.

Are there any other mods on the newly purchased vehicle or is it stock? Plus, like justin said. The idiot light might go away, but it doesn't mean the CEL isn't saved. It sounds like an overboost due to a quick downshift and the ECU got caught off guard. Would still like to know if the rest of the car is modded or stock.
