Check engine light
well i got my 4-2-1 one piece installed....running it for two weeks with no internal problems...but wait....i drive for about five minutes and that dreaded orange light comes on. The installers told me they moved my oxy sensor when they installed the piece so i havent talked to them since....any suggestions on why this may be happening and any easy remedy to avoid paying more money (i already ran a search and i didnt find anything concrete to help me as im sure this question has been asked before)
p.s. i have a 95 ex... |
RE: Check engine light
maybe the computer needs to be reset. pull the wires to the batery and let it sit for a good 5 min then plug it back and start it up. the engin light will be off but if it comes back on.... then you might have a problem. but most of the time it needs to be reset.

RE: Check engine light
I have the same problem, its the cat thats attached to the DC header what I've heard works is to buy a HI-Flo cat like Magnaflow and get it put on. If you reset the ECU it'll take about 30ish minutes for the ECU to pop that lovely orange light on again. I've been driving mine around for a couple weeks like that, no problems just a little laggy on throttle response. My Hi-flo cat just shipped out yesterday so I'll repost when I have it installed and see if it fixes the problem.

RE: Check engine light
No I can definately feel the VTEC kick in, around 4ish I can feel it. But it definately goes into some kinda safe mode, hence the laggyish throttle response. I should be getting my hi-flo cat any day now so when I get someone to weld it on I'll post back if it solved the problem.

RE: Check engine light
thanks a lot guys...i did reset and i believe it worked...havent had any problems yet...Chimera when you get that cat put on post a reply bcause id like to know if you sense any changes in noise or power...
by the way...do you know if the stock ECU for a 95 civic is programmable...someone told me it is but im not sure (he said 95 was the last year a stock ECU was programmable) |
RE: Check engine light
Yeah, I got a CEL when I relocated my o2 sensor. That high flow cat will give you a nice increase.
As far as your ECU, yes it is programmable. 95 was the last year of OBD-1. You can get your ECU tuned or "chipped" and squeeze more power out of it. |
RE: Check engine light
*Bump*
I got the highflo cat today. Won't be installed till the 13th I'll update again then. |
