Hello, I have a 99 TL and the miles per gallon that the car gets is slowly going down.

Any suggestions for budget mods that might help with fuel economy?

Thanks.

clean the EGR port--gets plugged and cars runs poorly

based on the experience of our megamoderator fsttyms1- with 350,000 MILES!! and climbing on an 00
every 75kmiles the intake manifold needs to come off and clean the egr ports out with a wire coat hanger and solvent/carb cleaner
see DIY section for details

call acura to see if yours was ever done under recall to install a thing in the egr passage-99s only
1-800-382-2238x5 need cars vin
they only do it once then its on you
same thing for 99 ignition switch- see if thats been done on recall

how are your spark plugs? 100k is acura dream on longevity
60-70kmiles and they are pretty worn out- enough to merit replacement with the correct ngk iridium spark plug
platinum was stock- iridium= gen3 uses them stock, and its an upgrade for us

using 91/93 octane with lucas fuel treatment will significantly increase fuel economy. recently on a trip from upstate ny 2 northern va i ave about 33-35 mpg. not bad for a 99 w/ 190k. even after city traffic i almost got 500 miles from a full tank. ok 468. i will attempt to clean my ports after reviewing the diy posts
