my car recently started to bog in it all at low rpms. i talked to one of my friends and he said i might need a new tranny. but i changed my spark plugs a few months ago and when ever i started my car when it was cold the rpms would bounce. does anyone know if this could be related? and how i can fix it

 

i'm in the same boat. I used my VAFC2 and lean out the low rpm in the narrow range and it helped a little. My car gets kinda bad when it warms up and starts squeeking. The squeeking comes from the intake manifold but I CAN NOT figure where in the IM it's coming from. I'm really having trouble solving this problem. Can anybody help me on this??

 

You won't believe me when I say this, but it kinda sounds like a problem with MAP sensor vaccuum. Maybe the TB mounted MAP is loose, or the firewall mounted MAP has a leak in the hose. Or I could be wrong all together.

 

not sure if its the same as my issue but I find that around 2k rpm its boggy. Like its kinda pulling me back in a way. Is this typical of h22a4? Never had a lude before so I dont know. Car drives fine but unless I keep it above 2k its slow as hell

 

Have you changed the fuel filter recently, never underestimate the "quick fix."

 

aight its your Oxygen Sensor. If your at cold rpm's and its like a 2.1k and it bogs down to like 1.5 somewere in that area . Yeah its your sensor . when you know its totally gone is when it does that sh*t all the time like my friends car.

 

is there anyway to check out your OS to see if it went bad? I dont think its the fuel filter, car runs fines unless its at low rpm. I havent noticed if this is when its cold or not but I think its like that all the time.
