New to me 2000 LC, 126k. Purchased 5 weeks ago. On our way out of a nearby state park yesterday, I noticed the CEL, VSC OFF and VSC TRAC lights on. I opened OBD Fusion app (iPhone - have a LE Link OBD-II reader installed) and pulled up code P1126 - magnetic clutch circuit malfunction. There were no other accompanying codes. I did a little research and decided to reset the codes to see if they popped back up. We drove another ~30 miles around town and performance was fine. No rough idle, no acceleration problems. It handled highway and city driving just fine. No previous mention of P1126 in the extensive dealer records from PO. 24 hours later, CEL and the two VSC lights came on again on startup. Again, no performance issues. There are many informative threads involing TB, TPS & APPS, but the fact that I have no performance loss has me a little stumped. Seems most others had some kind of accompanying codes. details - running 87 octane since i purchased 5 weeks ago. could this cause build up in throttle body? i'm assuming PO ran premium. - exhaust manifold very likely cracked. not sure which side. distinct ticking for the first ~3 minutes until car warms up. occasional ticking heard in city driving. - occasional drips on passenger side floorboard. i need to check AC drain & evap. had to recharge recently and things settled in between 35-40 psi. I'll be taking it to Edwin's shop (@green grass hopper ) soon for a base line. Guess I'll have to add this to the list if no simple solution pops up.
