i have a 2000 honda civic ex. i have a full AEM cold air intake and FULL Greddy cat back Exhaust system. and a 1 1/2 inch koning spring drop. when im driving and i hit 2nd and 3rd gear the car has real hesitation in lower rpm's. i will step on the gas and the car will barely move. what could the problem be.

 

That CAI you have installed will rob some of your low end horsepower. Also, some people have a problem with intakes leaning out their a/f ratio... meaning there isnt enough fuel in the mix.

 

mmmm then how would i go about fixing something like that. i just bought the aem v2 intake. and i realy dotn want to take it out.

 

Its a computer problem. You MAF sensor isnt reading the intake air right so its telling the ECU to inject the wrong amount of fuel.

Its either a BIG problem or a little problem:

The small problem is if the computer just hasnt realized that there is a difference in the air flow. Solution: remove both leads from the battery. Then (away from the battery) touch the two together, this will erase the stored memory in the ECU. Now re-connect the pos and neg terminals to the battery and start the car. Let it idle for about 10-15 minutes... dont touch the accelerator, make sure the radio and a/c are off, and just leave it alone. Then give it a test drive and see if that fixed it.

the big problem is if you damaged your MAF sensor (mass air flow sensor) while you were installing your intake. I doubt the dealership will warranty it since you broke it while putting on an aftermarket performance part. Solution: go to the dealership and get a new MAF sensor.

Another thought (if you dont mind spending about $50) is to get it dyno'd... it will be able to tell you whats wrong and where int he powerband it's occuring. You will also get a great idea of where you make peak HP/torque and where your a/f ratio is at.

 

is it an auto or a manual?
