Car Whistling like forced induction????

**NightRiderZ** · 11-06-2008, 05:40 AM

Every time i rev my car up, even in park or in gear it whistles as it revvs up...like a supercharger, so i brought it down to autozone and got it checked, said something was wrong with my maf sensor and there was a misfire in cylinder #7.......anyone ever have this problem or know what to do?? I do not want to drive it, as it will not fix its self and will only get worse....thanks

**NightRiderZ** · 11-06-2008, 06:27 AM

Not too sure the receipt was in the car before my sister dug through it

Could a messed up MAF make our Z's misfire?? I didnt understand why it threw a misfire code...thanks guys

Exaust leak?

**NightRiderZ** · 11-06-2008, 09:16 AM

Nah, its not a ticking noise like an exhaust leak...its more like a damn supercharger, kind of loud and some people have actually asked if i have a supercharger hehe....i mean it doesnt bother me i just wanna know if it needs to be fixed or if not will anything blow up on me??

i know when the car is in open loop on start up the ait pump is going and sounds a lot like a FI unit... also if oyu have an after market air lid you're going to hear "whistle" a little...

Mine whines too, but I'm not throwing any codes.

I used to have said whistle/whine.....I also used to have my stock water pump

My alternator makes this sound when cold.

codes are probably coincidence

Did you put in a throttle body air foil? My 96 would whistle pretty loudly when sucking in air after I added that. I would take the MAF off and clean it as well as the throttle body, and look for any obstructions or something there that would make it whistle. I agree that the plug is probably not related. Sometimes people are lazy and skip a plug or 2, or mabye they just need changed. Could also be the plug wire, possibly arcing?

Nah its not arcing....my 96' used to sound like it had a badass exhaust leak, i mean i would drive it and it would just be like TICK TICK TICK TICK...so i assumed it was an exhaust leak until i opened the hood and it looked like someone was shooting roman candles around in there hehe....so its not the wires, it drives just fine, actually i think its a freak and came factory with over 300rwhp

.... roast the tires in 2nd gear with auto =D...completely stock guys so it wouldnt be any additions i have made (yet)...

Check the airbox and all intake ducting. If there is a bad connection or a hole somewhere that might cause a whistling. If you are getting a misfire code you probably need plugs and wires. If they are original it would be some good maintenence to do them now.
