Car seems to be stuttering when taking off pretty badly....we checked timing and it has new plugs wires and distributor cap. Feels like there is no torque whats so ever....but after 4000 rpm no issue's what so ever....I have one CEL light IAC needs cleaned...any ideas or suggestions would be appreciated!
P.S. Could it be i'm using the usdm wires?

 

need help asap leaving for school soon and need my car on the road

 

haha, only 10 minutes between bumps, stuttering as in misfiring? wires shouldn't make a difference, fix the problems so you don't have any CELs and go from there

 

fix the idle air control alve problem before you try and figure naything else out.

 

replaced IAC still doesn't work properly? wirings all hooked attached? any ideas?

 

what car is this in?

 

i have the same problem, it sux bad! i have heard to replace the knock sensor...but then i was told if the sensor was bad that it would throw a code and im not gettign anything. then i was told to replace the O2 sensor, and im in the process of transferring schools so i havent had the chance.

 

93 civic coupe dx
knock sensor is good and my o2 sensor is brand new....throwing vtec pressure switch code and IAC...need help leaving for school next week AHHHH

 

your vtec pressure switch aint gonna cause your car to splutter...your IAC will cause your car to do that...make sure the plug that goes to your IAC is actually the IAC plug...

 

i would check the wiring that got relocated for the IACV jsut in case.

 

If you still have the IACV from your H23, use it, pretty sure it's the same. If you never had a H23 then nevermind. If you did but don't have it anymore, get a new one, they're relatively cheap.

 

using the one off my h23 right now still hasn't fixed the issue and doesn't rev when cold, then once at correct operating temperature rev down....i'll triple check connection....becuase something isn't right..

 

This happened to me once, end up being a loose connection on the TPS. Check that & your voltage too!

 

all connections are good....fixed the Iac and still have the vtec pressure switch code
changed out sensor and still throwing code? Checked connections all good

HELP!!
