Ok well i ve been having issues with my car since i put it back to stock from the turbo days, ive put 3500 miles without any issues untill I got a hard CEL, and then the car started to have a lumpy idle similar to a car with a real aggrssive cam and a bad tune. The idle fluctuates from 1800 to 2200 intermittently. when in gear @ low rpm's the car jerks especially in 1st and 2nd gear.
Now i tried to reset the ecu by unplugging the battery overnight and upon start up the next morning the idle was fine but after a few minutes the lumping idle began. Now as far as the vtec goes it does kick in but not really noticeable since the car is running extremely rich. When revving the engine the throttle doesnt feel as light as it did before. So i went to autozone and they pulled the codes for me and here they are:
P1519
P0133 X2 the autozone guy said it came up twice on the scanner
P0453
P0410X2 the autozone guy said it came up twice on the scanner
P0450

Before i go out start with this crapshoot can anyone tell me if theyve encountered a problem like this. BTW the car is a 01 berlina Ap1 with 24000 miles and stock with exception of a K&N intake.
thanks in advance

 

check the sticky thread to find the meaning of the CELs. The p0410 is a bad secondary air injection air pump, chances are the fuse has gone bad or the pump itself is bad.
