i have a 98 limited cherokee I6 auto and im getting a maf code? it has no maf i her its a map code really and i have a generic scan tool? it chugs and backfires when this occurs anyone else experiencing this problem?

 

It may still mean MAP. But that's not a typical issue most have trouble with.

When was the last tune up? What did the plug look like?

 

Try a different code reader or scan tool. And post the EXACT code you are seeing.

If it is a MAP code, that sensor can be tested with a meter and a manual. Also be sure that the vacuum line leading to the map sensor is pulling good vacuum.

 

the plugs and cap and everything are good it still runs like *** thats what it has to be

 

Not really.

It could be intermittently losing fuel pressure due to a failing fuel system, injector, regulator, pump, etc.

It could also be a coil going bad.

Unless you've tested the MAP sensor and confirmed, it could still be other things.

 

thats what i was thinking also how do i check my maf?
