i have a N reg ford escort mk 6 and when i have the air flow sensor connected the engine hunts and struggles to run but wen i disconnect the engine runs fine has the sensor gone? and in has a performance air filter could that affect it too?

[scottykilmer]

@lilgreyte20 yes to all, but try cleaning it first. Those filters can ruin em, NEVER use em on maf sensor vehicles.

Is erasing the codes using a scan tool must? Can removing the battery terminal for 10mins work?

[scottykilmer]

@richu27 most modern cars need a scan tool. Some can use the battery disconnect, go ahead and try.

@mike797 Fram used to make great filters but they've been bought out years ago, and are just another corporate business in search of profit. I try to get oem factory filters whenever possible. They cost more, but work much better. Scotty

@Rookerfy yes to all, can be any. but intake leaks are most common on that model

[Rookerfy]

@scottykilmer Could the lean conditions on bank 1 and bank 2 on my 1999 Ford Taurus Se, be caused by a bad MAF sensor, plugged fuel filter, vacuum leak, or a bad manifold intake gasket?

[scottykilmer]

@ballfor626 It could be, along with tons of other stuff. Best to analyze, not just replace parts randomly though. scotty
