Does anyone have any tips on how i can improve my gas efficiency other than a tune up? My 93 max is running about 10 miles/gallon. Does anyone have any ideas on what the problem could be?

-thanks

 

it could be your knock sensor runnin safe mode...

or drive speed limit all the time and rev under 2k

 

Are you up on your maintenance (30K, 60K, etc)?

 

tip: sell the 93

u should do a full tune up. Spark plugs, fuel filter, air filter, injector cleaner, tb cleaner, engine oil flush, etc

 

how do u check the knock sensor?..tune up the car and change the o2 sensor first

 

stay off the gas! use some seafoam in your vacumm line. it will not yeild exciting resukts, but could help! do spark plugs, and run some fuelk injector cleaner. those are the cheapies.

 

thats what ive gotten as a suggestion b4 but i have the slightest idea on how i would do so.. lol sorry man. im not "half of a mechanic" as some of these guys on this site. And who wants to drive speed limit. Lets be realistic.

-thanks

 

Silly question,

How do you know your Knock sensor is in Safe mode?

If its in safe mode, how do you get it back to normal mode?

Thanks alot

 

you know by checking your codes (won't turn on the light). Here's how: http://vbxmaxima.8m.com/ecu.html. If it's bad you'll have to replace it (read the 4th gen faqs for a how to).

 

holy crap 10 mpg? I just drove up to Boston yesterday... 220 miles each way and I averaged 25 mpg.. and that included about 6 freeway WOT romps on the highway upto 120... around the city here I get about 18mpg...

It really sounds like your knock sensor is toasted
