LS 430 Acceleration issues
My 2002 LS 430 recently started misbehaving. When I floor the accelerator the car hesitates 3-4 sec then starts to accelerate. Almost like it cant find the gears. and once it starts accelerating it does not really go like it used to.
Any ideas?

My 2001 LS430 had a similar issue. The problem turned out to be an erratic MAF sensor and a dirty throttle body. Dealer replaced the MAF sensor and cleaned the throttle body and now it runs like new again. The transmission was not touched.

The check engine light was NOT on when my LS430 had this problem. Dealer did say there was a history of some MAF codes but they did not cause the check engine light to illuminate.

I had it diagnosed and it turns out the K&N filter I use was allowing too much dust/oil past and built up on MAF sensor, cleaned that, problem went away.
