put-put smoke

[vgeezy31885]

Yesterday i noticed my girlsQ has been putting outsmoke. We got the sparks plugs changed about , 15000 miles ago, now were at 199,8xx. I dont know if its scheduled for another tune-up cuz it shakes at idle. Even if u step out the car u can see it shaking. We just got the fuel injection cleaning done like 3000 miles agowhich stopped the shaking and rough idling a lot. It was about 70 deg here and i figured it shouldnt have smoke coming from it while at a red light. Is it burning gas? P.s. - We havent drove it in about a month so everytime she ask me whats up, y its shaking, i just say the same thing,"Let THE CAR WARMUP" .iT Probably aint got **** 2 do w/ nothing, but my shirt dont say Infiniti, Midas, Meineke,... none of that on it. Help me Plz,whats the problem?

Sorry, but really can't tell by your description. Black smoke? Blue smoke? White water vapor? We can't tell.

If it's shaking, why don't you ohm your injectors ans do a power balance test?

Nah,definetely no black or blue smoke. its not thick white either. its the normal smoke ,it just doesnt come out the exhaust smooth.The best way i can describe it,is if somebody is blowing out smoke real fast instead of 1 breath. (i knowthat sound crazy)

P.s. When i mean put-put, i dont mean like a hyundai or kia, it still drive nice as ****,just has avery slight rough idle and shakes until is haswarmed up and driven for like 10 min. But if u stop and start back up, the carstart harlem shaking again

Got a digital voltmeter? Ohm your injectors and let us know the results.

the engine light came on a littl while ago and it was driving terrible. I took it to mr-tire and got the fuel injection cleaning done and the light hasnt come on since. We havent driven it in about a month so i dont know if i just need to give it a chance or what? Ill try to find a voltmeter to do the test.P.S. Where is the MAF sensor so i can check that?

The MAF is attached to the air box (air filter) but don't worry about it for now.

Cleaning the injectors ensures that they flow properly but checking the resistance verifies that they are operating (opening and closing in sync) electrically. Two different beasts. From the description of your problems it sounds like injectors.

Buy a voltmeter or phone a friend and follow the instructions in the link posted above. It's a really simple test that shouldn't take more than 10 minutes and requires no tools other than the voltmeter. Ohm your knock sensors while you're there just for fun. It's the plug next to the FI plug. Good luck.
