make sure that the only solvent you use to clean the MAF is marked "MAF sensor cleaner" and for everyone else reading this, do not clean a pre-1995 MAF with any solvent! - not even MAF cleaner or "MAF-safe" cleaners

unless the car has been run without an air filter, which would be very strange on a car with 31,000 miles, then what makes you think the MAF is not working, that is not something that has issues on a 96 model

I'm also checking the maf wiring just to be cautious.

the LS400 has had some EGR issues, beginning with the crinkled section of the lower EGR pipe cracking
