hello I have a 900 , 1996. after my last visit to the garage, the check engine light is going on and off several times every day. I checked the engine with the thec 2 instrument that confirmed that the engine is working perfect. It annoys me, what should I do?

This is the first I have seen this one..
The CEL being on has little to nothing to do with the quality of running from the engine.
The CEL is emissions based. The code, having the exact code will help.
Then, all the maintenance work has to be up to date...
Also, all the details are helpful.

It might help if you tell us what work was done at the garage. It's stimulus and response. The car wasn't making CELs, you took it to the garage, now it's making CELs. If they changed O2 sensors, they probably put in an aftermarket sensor and maybe messed up the wiring. Just a guess though... Ron
