I have a 96 and I replaced the MAF once and I am very sure it came from a 97 or 98.

I am wondering though what the plug on the MAF looks like. On mine its oval but I was going to install my new one and it was rectangular with rounded corners.

So the store looked at the other one in stock and for other years, they were all the wrong plug but they did not have any 98 ones in stock.

I suppose I could get a new harness, but I was wondering if anyone else ran into this and is there any difference in MAF sensors.
 
The 96 and up should be a rectangle with round corners. If you have a pure oval port, then its prolly a 95 and earlier meter.
 
I have a 94 in hand now. I am more worried about a change in resistance, etc that may affect things than I am about the plug. But the one I have has an oval plug. Will install tonight!
 
I believe that there's nothing that different from an OBD-I plug and an OBD-II plug. That's why vendors sell adapters to run OBD-II MAF units on OBD-I cars. I ran an OBD-II MAF on my 95 SHO for quite a while without issues.
 
Good to know. I dont even think my MAF is bad though anymore, but its just to rule it out.
 
I've found that cleaning the filaments helps immensely - I've never had to buy a new or reman'd MAF, ever.
 
Oh ya, I have cleaned them. But remember there was a silent recall on these and they would go bad at some point but I am not sure what year they were fixed. I got a new one for cheap, so not too concerned if its not the root of the issue, just want to rule it out.
 
You have an xcal... log maf add counts.... that will tell you if the sensor is working, try and get a log with lots of different load driving....
 
Add Counts are really voltage that has been disguised, Ford works in add counts, the range is somehting like 0-1000.... and they correspond to 0-5v readings.... there is a way to convert them with a nifty forumla... lol
 
Charts are pretty, but I have no clue what the f they mean... :)

So and idle only in park, thats the only log I have at this moment, show MAF adds spike at start up and calm down and level out pretty flat and inline with spark.
 
What do you mean by flat line :D

That definitely doesn't sound good add all.... add counts should go up consistently with load. What does load look like?
 
If I have time I will get a new log. I think that last one was a idle log too.

My software SUCKS and crashes a lot, makes a mess of figuring this scrap out. Hate windows...
 
I got a fresh new log file....

This is from a slow roll onto a back road creeping up to WOT without shifting down, hence the slow accel rate to WOT. Then bringing it down via coasting...

Whats up with spark source?
