1992 Mazda Protege !992 mazda protege still idles high

I put in two new sensors for temps. Still idles high after it get how. Then at stops idles high and when you put your foot on the gas to hard to will cut out. sometimes it starts and sometimes it gos. But it cuts out a lot. It got coded at a a very good shop(it was free) the code read 09 something like that. which told us its the both temp. sensor, and replaced them new. Any more Ideas? They want a lot to have your codes read for you. I am waiting a a guy who has worked on cars and has a new code read for both I and II. He is on vaction. he cheap. Half the price then shops or lesser.
The other thing is it does get gasy smell a lot. anyother things you can come up with until he comes back which can be weeks.
