Last spring I put a new motor in my car and removed the smog pump. I plugged the holes in the heads and a couple of vac lines. Since then, when the car is cold it will kind of "pop and miss". But if you floor board it, it will go and run fine. At normal temp it runs okay, but engine light still blinks. My codes read Smog Pump and EGR. Just wondering if anyone out there is running the EGR eliminator kit found on ebay that plugs into the electrical connectors and fixes this problem.
