i checked my crankshaft position sensor location,but i found that my car has a s13 tranny instead of a s14 which it doesnt have a cps on the s13, my question is will i have any problems passing smoke check because of not having the cps on my car?

Try to get the emission test w/o the CPS and make sure the CEL comes on and goes off when it suppose to and see what happens.

Try cleaning the mass airflow sensor with an approved cleaner, don't work its your shot-also check its wiring
