I have a problem where I hit the gas my car starts to shake starting at 2k rpm. It does not stop vibrating. I try to cruise going 35-45 mph but it continues to vibrate. I changed my whole suspension about 1yr ago. I did everything brand new. My inner rod, out rod, control arm and bought gr-2 with s-techs. I thought vibration might have been coming from axles. So I changed the axles and they are now only 2days old. I figure it is not suspension since its still vibrating. My car starts up right away with no problems at all. If i put the car on D the idle drops from 800rpm to 750 which i think it's ok. I cleaned throttle body n maf but nothing. A local org member said my maf sensor is bad to change it. I am planning to buy a brand new maf sensor sometime this week. I hate to drive like this cuz I have a 2month old baby and it just dont feel safe. I asked him if it was coil packs but he said my car wouldn't constantly vibrate if it was. Any suggestion would be great.

 

Go for the maf. Try not to get from the dealer its really overpriced. Get OEM only (prob off of another car) because ebay maf isn't that great

 

Well I know there is a place where I get it for $44. Brand new down here in Miami. I have a z32 maf sensor sitting at home not knowing if it works or not. I found it yesterday. Maybe I will try that once I find out how to wire it up.

 

Go to jy and get 1 bro

 

Well I just bought a brand new maf sensor for $43 on ebay. It arrived today and problem solved. My car so much better. Now I have backfiring problem which I think it might be my coils. I replaced spark plugs and it didnt solve the problem. I have to wait to get paid or sell items to buy some coil packs.

 

Search for some general diagnosis how-tos before you put more money into this. It seems like you're throwing parts at your car without actually checking if they're the problem. Ignition coils can get pricey. Are you backfiring or misfiring? Misfiring is more common and could be more than just the coil packs (injectors, wiring, etc)
