Ltb2 10.5
Ltb2 10.5 I am really confused. LTB2 is running 10.5 at idol while LTB1 is 0 to -2 in park. When I give it 5% TPS LTB2 goes to 5.5. Drop it in gear and LTb2 goes to 4 and LTB1 is -2. I changed the 02's-nothing. Checked the entire exhaust system-nothing. Now what? just to make sure +10.5 is lean correct.
Can this be from a 236 595 112 Cam on an A4?

Reply I changed both 02's, looked over the vac lines, coil packs and plug wires are showing spark with a spark light. I'll pull plugs to see if they are fouled. Is +10.5 rich or lean and can this damage the motor if it is just at idol.

Reply I don't think it is engine failure. The car is running real strong. I did just reset the valves (adjustable) they were way off and the compression was real low (165 before set and 195 after). For a ECU reset, I disconnected the battery and touched the cables together for 30 secs. no help.

Verdad Gallardo Reply I took it out for a cruise tonight and it is only running lean at idle in Park and N. At a cruise LTB2 is at 3 to 4 and LTB1 is -2 to +2. There is no backfireing, no codes, and no misses in the motor. It is really weird in Park and N as soon as I let off the gas LTB2 goes right to 10.5 and will go as high as 16.
