Good evening,
I just finished installing APR's boost tap and gauge (of which the gauge was a major pain, for a number of reasons I'm blaming APR for). I had a little issue.
Intake was completely removed, battery was completely removed. Followed APR's written instructions very closely. Allowed car to warm up fully (roughly 200F oil temp) before installing. Hole was punctured in manifold while manifold was warm-ish.
Everything installed normally, everything was put back together, everything was in its original place that was there before.
I go to start the car up, and I get a CEL and a very rough idle after start. Idled as such for about 10 seconds, dipped, and shut off. Again, started, seemed normal for about 3 seconds, then began to dip and shut off.
Third time, started a little rough, then picked up and held steady. No issues. Drove around the block with no issues. I cycled the engine about 4 times when I returned, no issues.
Using the Accessport, I read 4 codes: One for random misfire, One for Cylinder 1 misfire, one for Cylinder 4 misfire, and, for some odd reason, one for an inefficient catalytic converter (which I haven't gotten before. Input would help!).
I'm assuming a little plastic got into the manifold from when I punched the hole, and that caused little misfire or some skittishness when it made its way into the engine. I really have no clue. There's nothing else that I know of that can explain this in a reasonable way.
If you have anything you think it may be, please let me know. Otherwise, give me peace of mind in knowing it was just a little hiccup.
