It was colder out this morning than its been at 52 so i started it up and it idled good for about 2 min then went ruff and at the same time i noticed more vapor coming out the exhaust so turned it off and back on but it did the same. Fairly sure the intercooler is slightly leaking and now thinking back on things i believe a past owner used an stop leak to seal the intercooler leak and when i flushed the system i opened up the leak. So is there a better intercooler avil or just try to find an good used or new oem. Looked on ebay and found a few used but they do not say if they have been pressure tested so they would be a gamble.
