Hello, I own a 1997 cadallic catera.
we had a code that told our tech that we had excess gas fume leak, crank sensor & no. 6 hole is missfiring, he reset the codes, the check engine came back on(car ran rough). He rechecked check engine cod and only had no.6 missfiring in code he read, so he checked compression, it was 125 so he checked & replaced no. 6 spark plug(bad plug), he also replaced exaust manifold gasket because he had to remove to fix a broken stud in exaust flange. We got the car back, it ran fine no rough idle for aprox 1 day, the check engine light came back on, I had it checked and a p0175 too lean(bank 2) it has been running rough. And will not start after it has been runing, It will start again after letting it sit for aprox 15 to 20 minutes.
It runs rough and some times dies and you have to waite a while then it starts.
