at that mileage I would consider looking at a new fuel pump. it will be difficult for your mechanic to ascertain a week fuel pump but it will certainly cause problems for you on a ctsc
I took mine to my mechanic and asked him to do whatever he felt like he needed to do to give me a go/nogo recommendation. He's worked on my car for 8+ years, so he knows it pretty well. I think the only new thing he did was a compression check.
Car has 151,000 miles on it. He told me to go for it, but to budget for a clutch sooner or later.
