94 LS400 - sluggish acceleration, and low RPM pinging

Apologies reviving this dead forum 14 years later. Seems like och never found a solution, wonder if he's still got the car

Just wanted to add since i've finally found my solution after years. I've done basically everything och has done and have the same problems.

I recently swapped igniters with my mate and low and behold, CAR IS FIXED! I can finally go up a hill without flooring it

I've never heard anything about a partial igniter failure so thought I'd share my insight. I had no codes for them, but it appears partial failure is a thing, although it must be pretty rare if there's no posts about it. Hope this can help someone else out with their car

In my experience, their either work, or they don't.
There is always an exception to the rule though!
Good to hear you found the solution.

P/N for Igniters (UCF10 09.1991 to 10.1994) are 89621-12010 and 89621-12050
You need one of each. Not sure if they're swappable... someone smarter than me would probably know
