i just recently removed the muffler on my monte and did a turndown anddid a cold air intakeand ive noticed that the throttle responce has been slacking. I have to hold in the throttle almost all the way to get it to 3000 rmps and get some go, is this normal with those kind of mods and would a throttle enhancer take care of that?????

 

hmm i havent heard of that b4...what did u d for your cold air intake? while doin it did u possible damage ur TB? or possibly ur MAF sensor?

 

No the tb is fine i didnt even go up that far i still have the stock inlet i just added a kn filter at the end and removed the stock airbox im waitingon the crome tubing, not much of a cold air intake yet but it worked it still sucks a alot of air. What else can cause problems with the throttle responce??

 

I'll try to post a pic.

 

No, throttle responce should actually improve.

The TPS enhancers are garbage. All they do is tell the car that at 70%+ to open 100%... just push the gas petal down the other 1/4 of the way.

 

are you saying you have no muffler at all????

 

You should check to see that the TB and MAF Sensor connections are securely plugged-in, otherwise the Engine will operate at a Default Duty Cycle and not respond to the Throttle variation until the PCM gets the correct values from those two sensors and responds to their signal outputs.

 

you might have to reflash the computer for all your mods. so that the car can run normally.

Also it might be you have so littel back pressure the readings are off.

you took the muffler completly off and also the resinator ? is this right?

 

Correct no muffler i kept the resinator and the cats though i was thinking of a res delete but im afraid it will be way too loud and not sound good.

 

your trouble is that the heated O2 sensor is not getting and holding enough heat in it due to very low backpressurein the exhaust.it's flowing too well and too cool. it needs a performancemuffler installed. that will get the O2 readings backto parameter.
