I have a 351W in my fox. I didnt do the install so I am chasing problems as they come up.

I know this car has 24lb injectors on it, but I am NOT positive it has a 24lb MAF on it. The car runs really rich...

Q: I assume the 24lb injectors will still run with a 19lb MAF but it would be rich, right? Or would I be fouling injectors, etc? Sometimes I get a pretty bad idle surge that goes away if I rev the engine pretty good. Any thoughts?

I should also let you know that there is an 89mm(i measured) MAF(looks factory ford) housing in it as well.

That is a welth of knowledge and makes me rethink a bunch of stuff

Yup, Ford cal'd the PCM, not the MAF, for injector size. That's why you can take the sensor from the housing and swap into MAF's like a C&L...and cal it via a sample tube change.

Thanks John. I assume thats why I'm running rich. Probably need to get my hands on a twEECer sometime soon. I will be stepping up to 40-50lb inj and bolting up my s-trim after i figure out my small problems like that steering issue.
