88 DL Wagon w/ EA 82. Recently advised to CLEAN MAF, bought MAF Sensor cleaning spray, removed sensor from Body, sprayed it, let dry and replaced. Was VERY careful in Removal, Handling and Replacement, but have suffered Mileage loss shortly thereafter. Tested Sensor in accordance with Chilton Manual. Can any one give me some advice on testing MAF, was it a mistake to mess with it in the 1st place??? Any suggestions as to where to pick one up???

I would look at a junk yard, and bring your dmm to check the ohms before you buy it

DL had spfi motor? Either way is your only problem bad fuel economy?

Yes to the SPFI Question, Idea's?

Any possibility of an air leak? A fair amount of old hoses and connections have to be moved to get the maf off. Something may have been distubed?

 

I've not had any trouble with maf sensors.

tysons92loyale, you mentioned testing MAF @ the junkyard w/DMM. The manual I have gives only how to test by applying 12v across 2 contacts and checking from Neg contact to a 3rd. Do you have specific Resistance #'s to check for a GOOD MAF???

Where is that link to the factory service manual when you need it?

 

iirc, they listed ohm tests.   Nothing you did should have hurt it, unless somehow mixed up pins when supplying 12V?
