Re: Bosch type 3 yellow injectors.
I purchased a set of Bosch 3 fuel injectors from Souhbay. After installing them I noticed my BLM was 160 instead of the ideal 128. Not sure what that means. I was concerned that it would not pass the emission test. I recently took the car for inspection and it passed the emission test. Car runs great with the Bosch 3's. Maybe your having other issues. Have you tigthened the runners bolts. After severl weeks of cruising, I found found several runner bolts loose. Have you checked your EGR. If the EGR is stuck open at idle, the car will run rough. Wish you luck.

Fred, blm counts of 160 means the ecm is adding as much fuel as it can. Keep an eye on these, and consider turning up fuel pressure a lb or 2, or more depend on on blm. Work toward 128.
