the issue is that obd 1 and 2 don’t work on my car and i can’t figure it outPull ECU codes.
no there isn’t there is one right as it comes off the air filter thoThe cold air intake you installed may have disturbed the way the air flows through the MAF. Is there a bend in the tube right before the MAF?
i actually already own that obd reader and the obd one doesn’t get anything to itYour car is OBD-1.
You can use a cheapo scanner from Amazon or use the method below:

Dump the codes: Codes may be present even if the Check Engine Light (CEL) isn't on.
Dumping the computer diagnostic codes on 86-95 Mustangs
Revised 26-July-2011. Added need to make sure the clutch is pressed when dumping codes.
Codes may be present even if the check engine light hasn’t come on, so be sure to check for them.
Here's the way to dump the computer codes with only a jumper wire or paper clip and the check engine light, or test light or voltmeter. I’ve used it for...

the maf censor isn’t on clamps it’s on bolts so i’d have to loosen them and twist it but i’ll try it tmr and see what happens thank youSometimes if you rotate the MAF to a different position it helps. Loosen the clamps that hold the tubing to the MAF. Rotate the MAF 90 degrees if you can and retighten the clamps. Give it a try and see.
i figured it out cylinder 4 is misfiring and im trying to figure it out its not the distributor cap or rotor cs i js replaced those and they dont look bad and i js replaced all the wires after this happened so idk why its doing it. i hope its not a bad cam or something cause i was hearing an intermentant clicking above cylinder 4If you can’t rotate the MAF, you can always put the factory air filter stuff back in and see if the problem goes away.
By the way, the factory setup is already a cold air setup. You probably gained nothing by removing it. Is the new filter exposed in the engine bay?
Also, changing to long tube heaters involves O2 sensor being further from its stock location and typically involves wiring extensions. How did all that go? Double check all of that and make sure wire connections and wire securing is good.
Just out of curiosity, how did you discover #4 misfiring. Is that cylinder not firing at all or is it randomly misfiring?i figured it out cylinder 4 is misfiring and im trying to figure it out its not the distributor cap or rotor cs i js replaced those and they dont look bad and i js replaced all the wires after this happened so idk why its doing it. i hope its not a bad cam or something cause i was hearing an intermentant clicking above cylinder 4
well i knew it was misfiring js off by sound so i did the water bottle spray test and that one was a little hot but no where near the others so i checked the spark plug and changed the wires cause i already had new wires and it was still doing itJust out of curiosity, how did you discover #4 misfiring. Is that cylinder not firing at all or is it randomly misfiring?
yes and it won’t read the car on or offOn the obd connector, the 94-5 GT models have a scanner connector under the dash, that connection does not work, the obdl is by the right/passenger side at the back of the shock tower. Is that the one you're using?
okay i’ll do it after school and ill let yk what all the readings areIf you’re sure that the spark plug for #4 is firing as it should, the next step in my recommendation would be a compression test.
Try the paper clip/ jumper wire method and reading the check engine light flashes, should be plenty of YouTube videos sh9wing how, if it still won't out put codes chances are high ecu needs repair or replacement. The obd2 port is present on 94-95 v8 cars but its not connected to anything so it won't out put any readings,it was there for the v6 models.yes and it won’t read the car on or off
