ok i need some help? i have a 93 civc ex with a z6 and i need 2 know why my baby always burbles from my exhaust when i downshift or decrease speed!!! is it because i am running rich? could it be my timing i just did a timing belt change like a month and half ago? Dudes i need some help. all thats dun 2 it is short ram intake-dc headers -catco hi flow cat- ka power exhaust - no p/s no a/c- i am not sure on fuel pump because it looks like it was replaced before i got the car.

Blowing any smoke?

My car "gurgles" a little bit too, but that's because I have a big header and a test pipe.

my car burbled because i was runing rich. Check ur TPS Sensor which senses ur throttle, is it properly adjusted?. Faulty O2 sensors can also cause ur car to run rich. Just recheck ur TDC marks on ur engine also. And ur spark plugs, cap and rotor.

definately go over your timing again but ive seen cars with high flow cats or gutted cats do this also did you have the same problem b4 you got the high flow?

i don't think i did do that before i changed it but i changed my 02 before when i had the code i just wasn't sure on the wiring, i had a cel at first when i got it changed and then rewired it and it went away. i had a bosch one first and then i went 2 denso. Is which 1 is better? i will try 2 check my tps and my timing, when i did my timing belt though and started my car it didn't backfire but it kinda would like make a little pop noise so i advanced the timing and it went away. oh yeah i i've checked my 02 before and the end was all black. what if my exhausts piping is all jacked up will that cause any of my problems. thanxx guys!!!
