[QUOTE="WhiTriCobra, post: 10594886, member: 77590"] With a small vac leak, sure it'll run fine but if it's out the back lower intake, you'll know. But with vac leaks, usually your rpms could be a tad high. I've had that problem on a few cars before. I just know i've had that same code, cleaned everything, check vac leaks and once i changed the 02's it went away. Why, cause it's the 02 most likely sensing the problem. It's electrical, so anything is possible. Can it be a vac leak, sure can. Dirty MAF, yes. The MAF would have been the first step and cleaned it. Vac leaks are not hard to detect, move stuff around, follow hoses and so on. I've had a vehicle not start or it would stall, shift hard and so on...all because of a bad tps sensor. [/QUOTE]
