I went to go check my spark plugs because my car has 85k. The plug was in OK condition still can be used. I put it back in i go to start my car and it idles rough at 500rpm or lower. I go to drive and i floor it and it bogs down it almost wants to shut off after I floor it. Idk what to do i did everything right. ANy suggestions???

 

try resetting the computer, remove the negative battery lead for like ten mins. you gotta reset your sunroof and auto up/down windows after reconnecting the lead.

 

I just changed all of them with NGK Laser iridiums. the car seemed to idle fine but when i try to rev it it bogs down. As of now i have the terminal off.

 

i just put the terminal back and its still idling pretty rough =/ hmm

 

Why did you only pull one plug then start it? Did you mess with the gap on the plug at all? Did you make sure the "coil on plug" pack was completely seated onto the spark plug?

 

Just to make sure I put everything back on right ive never dealt with coils only with actual spark plug wires.

 

No need to make a thread here and in the lounge. Only one thread is needed.

 

try using some sea foam in the motor and gas tank worked for me might just be build up in the motor from bad gas

 

clean the mas air flow sensor to

 

do you have a check engine light on?

 

You alreadyhave a thread for this. you dont need two!

 

YEa the check engine is on.

 

Get your CEL checked
Clean your MAF sensor * go to store get MAF sensor cleaner
Do you have Cold Air Intake? is your intake's small tube is closed and the engine have a small breather on the side? If yes then throw all that out and connect them back together with a hose
Do a Seafoam treatment


i did all these and my idle got much better!

especially when the AC is on... oh god my car use to shake like crazy on idle

 

do the spark plugs come pre gapped because people are telling me to check my gap but at autozone they told me they are pre gapped.

 

pre gapped or not, you should always check them. The gapping tool is only $1. Don't listen to auto zone about car specific issues. Get the code checked and report back.

 

OK. I scanned the check engine light. It gave me 10 different codes. MAF and VAF, It said that all the coils are malfunctioned. I clicked the erase option and it deleted all the codes but the MAF. The coil codes never came back. I went and bought MAF cleaner and its still doing the same thing. Any other tips or suggestions????

 

I'm having the same problem!

I posted it on clubsciontc and couple of those guys are saying its my Torque Converter.

Has it stalled before? Mine did about 7 times within the past few months. Once the car is driven least 20 minutes; the idling is gone and is running like a champ!
