I have problems.
I was running 19lb injectors with the appropriate MarkD chip to accompany the 274 cam from Bimmerheads. It was fun and it ran well, if a little rich in the lower revs. SSSquid came out with their chip and I thought I'd give it a whirl, supposing it would be more refined. I installed the chip and some 17lb injectors that were recommended, but the start up was less than desirable (when isn't it?).
Here's a video of the issue, hopefully you can make out what's happening, but I know the sound isn't great.
The car will fire up almost immediately but I have to hold the gas to get it to keep running at just 200-300 RPM. If I keep holding the gas, it will shoot up to however high I want, and if I hold it steadily at say, 2500 RPM, after a few seconds the engine will suddenly drop down to that sub-500 RPM mark. Repeat. The check engine light is on as well.
As usual, I have no idea where to start with diagnosing this that won't be a useless escapade. Any suggestions?
