sup guys

i just had this prob goin on like a week ago, i felt it when i was driving in 4th or 5th gear at low rpm then when i try to step on it the car will lag a little then it will start to go my car has 140k on it could it be the transmission or what??

 

Ignition coils? Are you feeling a "miss" at low rpms, or just lag?

 

How low of an rpm are you talking about?

 

Put your stock intake back in place.

 

around 2,700 RPM
the car like keeps on cutin off but not for a long time like a second or so then it will start to go

 

Check for knock sensor code

 

i got a new knock sensor like 2000 mile a go

 

MAFS, check 2 see if you have this code. i was having this same problem and got the code for MAFS. i took it off and there was a thin film of grease and dirt, i cleaned it off an and it was ok from there on. MAFS= mass air flow sensor, in-case you didnt know. good luck

 

I was am having the same problem but the CEL doesn't come on... Where is the MAFS? what does it look like? Help. Thanks!

To check for ecu codes:

The MAF is located in teh throttle body.
Here's how it looks:

i just cleaned the screen with a semi damp cloth and got all of the gunk off, i didnt touch that lil sensor inside.

 

I just came across these threads, might be bad coils

Somthin similar happend to me about 6 months ago. If it shuts off at low RPMS's and it feel like your car can breath then it might be your catalytic converter is clogged. this happened to mine at about 126,000 miles and i just replaced my y pipe with a performmance one and my cat with a test pipe. Although if you have to worry about emissions get a hi-flo cat.
