Hello , hope everybody is doing well , very poor gas mileage for some time , I have an a air / fuel meter and it fluctuate from lean to the firts green light on the rich side all the time, the car feel is good , no intake leaks , replace air mas meter , fuel regulator not leaking , new spark plug wires, caps and rotors

check pulses for the check engine light and it comes a total of 17 codes , un known code , this problem I already got it for some time , posted also

I don't remember why I change the module the have 4 fuses , the module number is 014 545 34 32 ,,, my vin is 124036 1b 475366

I mention on a previous post about the check engine light on

I don't have nothing to test any more the systems so I will to find a shop near 91791 the has the experience , I took it sometime to a shop but they could not figure it out

Thank you Carlos

How bad is the gas mileage, and is this city, or highway, or both?

Also - are you 100% certain the problem is not an intermittent odometer? This can make it seem like your MPG is terrible.

Hello , both , I did not reset the odometer but since I owned since 1999 I know is done , If does help I can wait till the light is on and add fuel to the firts quarter and report

another problem I have is the under 1/2 tank when I go in left turns on the Hwy fuel comes out the drain hole on the left bottom corner of the filler neck next the gas cap , I disconnect the check valve by the ABS pump because the gas tank will keep a lots of pressure , thank you
