Ok , as usual the light "Check Engine Light" goes of.. System to rich , because of intake as usual.. , but my car smells funny when im putting the gas pedal down of course.. like it really is running really rich. IS this normal for a simple intake mod? stinks..
did you reset the ECU after you put in the intake?
did you fix your o2 sensor yet?
02 fixed , when I did a scan on the computer it just said to rich..nothing about an o2.
No its not normal.
Did you reset the ECU parameters (ie disconnecting the battery for a while)?
Im wondering if that is a bad reading. I mean shouldn't the engine be able to accomidate a rich condition fairly easily (atleast in a mostly stock car ~ ie no FI).
yes I reset the ECU , then it just came back on..https://www.thegalantcenter.org/styl...efault/sad.gifQuote:

what brand is the o2 gauge? really shitty o2 gauges weaken the o2 signal, so the ECU might be getting a flawed reading and is deciding to just keep things uber rich to be safe about it. i've heard horror stories about those generic o2 gauge on ebay.
o2 gauge?.....you mean sensor right..?Quote:

where did u get o2 gauge from?? he said he found out it was running rich my running a scan tool.Quote:

I disconnect the battery and check the MAS and Intake. Everything looks okay. I reconnect the battery a few hours later and the problem still exists. I then leave it off for a day and it seems to be okay but later that day the problem came back. It was so bad that I burned a 1/2 tank of gas in only 12 miles. I kid you not. So I disconnectedthe battery again for a few hours but that didn't help. I then left it disconnected for a few days and that did the trick. I never replaced the O2 sensor no replace the fuel filter. I probably should but I haven't had any problems since. That was about a year and a half ago. Knock on wood.
peano: I bought the 02 sensor used from a vehicle iwth 29k miles on it
Reelax: it does smell like eggs
BGR: perhaps I should try that , I wanna see what reelax was talking about first about the cats..
I may have to do what BGR did and leave it disconnected for about 2 3 days..
