Hello everyone ! This is my first post on here , I am having some problems with the drivability of the car! When in stopped and begin to go my car acts hesitant and once I break 2500 or 3000rpm it feels nice and steady! When I floor it it seems to be just fine and hits vtec hard ! I am on my 3 tranny this new one has about 30k on it now ! I replaced the plugs and they are the 4 tip ones soo they can't be gapped ! Please help !! Thanks Eddie !

is your batt good? alternator new? its only in first gear second?....?

It's all gears mostly 2,3,4 and the bat. Is a. Year or so old and I don't know about the alt.

does your D4 light blink? and is it hesitation to shift gears? or is it feeling more like a cylinder misfire? sorry for all the questions it just helps me understand it more.

It hesitates when I begin to go , and it hesitates while climbing up to the shift point then shifts smooth! There is also a raw gas smell when the car is just sitting I have a check engine light that just came on codes p0156 p0143 and the d4 Light doesn't blink!

those codes point toward your O2 sensor. maybe try replacing that and see what happens. or make sure the sensor isn't super dirty or anything

Your o2 sensor isn't functioning properly. Cleaning with with electrical cleaner is only a temporarily fix. Just buy a new one or used one on the forum. Your car is most likely running lean. My car was doing the same and would stall on cold starts. I would replace your spark plugs as well since I ran like that for 3000 miles and my spark plugs were shot.

Ok where can I get the cleaner! And is there a DIY page on cleaning them?

i dunno about the DIY and i think you can use CARB cleaner. I THINK! Don't take my word for that. Check the "Master DIY" thread
