Need Your Valuable Expert Advice For 92 Ls Engine Problem

[sf lexus lover]

Hi Everyone,

Thanks for all the great advice that I have read from the site!!! I have a 92 LS 400 w/ 110,000 miles on it. Baby it all the time. The timing belt broke - really melted!!! I had it replaced along with all the related parts ,tensions, seals etc,. Plus now was the time to change cap and wires. After 50 miles the check engine light came on. It was code 25 - lean fuel mixture. all o2 sensors are fine. Dealer can not figure out the problem?? Could the broken timing belt cause something else to come unglued??? Runs fine except for the check engine light??

Thank You in advance of all of your advice.

Check the waterpump, camshaft position sensors, crankshaft position sensors...theres a hundred possibilities.

Did the dealer tear the engine apart? DId they set the pistons/crank/cams to the right positions before reinstalling the belt? All these are questions we need the answers to. Your engine is non-interference, so I doubt you did anything too awful. Probably just a sensor somewhere.
