jluster05 Posted May 3, 2007 Author Report Share Posted May 3, 2007 Maybe. Can I go ahead and assume that the flashing CEL is a direct result of my P0400 or could something else be attributing to it..does the flashing mean theres another code too or the one code you have has gotten worse? whats the best way to check if its a vac leak? im going to get my codes repulled..

mohamedeladawy@hotmail.com Posted May 3, 2007 Report Share Posted May 3, 2007 that crack will prolly be the reason why ur acceleration is hesitant. i had the same shit too and after being replaced, my acceleration was back Quote Link to comment Share on other sites More sharing options...

Renboy Posted May 3, 2007 Report Share Posted May 3, 2007 Your fuel trim and egr are vacuum controlled, that eliminates 3 codes. Random misfire can definitely be attributed to an egr that's open when it's not supposed to be, that's 4 down. And for number 5, I don't know what that code is, and don't feel like looking. Someone post what it is. Quote Link to comment Share on other sites More sharing options...

///BHRpowered Posted May 4, 2007 Report Share Posted May 4, 2007 a solid state CEL means you need to get the problem looked it, a flashing CEL means get the hell off the road and have it fixed right away Quote Link to comment Share on other sites More sharing options...

mohamedeladawy@hotmail.com Posted May 4, 2007 Report Share Posted May 4, 2007 go to autozone or pepboys and buy that plastic piece for like 20 bucks. its in the ricer section. i would then take it, paint it matte black and replace that ugly hose with it. thats what did except i just removed the entire airbox and put a cone filter instead. if u are located in the nj/ny area, i can even do it for u free of charge.

mohamedeladawy@hotmail.com Posted May 4, 2007 Report Share Posted May 4, 2007 02 sensor? its the closest sensor to the exhaust or something i believe. im not sure. and more than likely am mistaken. p.s. hilarious avatar! Quote Link to comment Share on other sites More sharing options...
latinopikachu Posted May 4, 2007 Report Share Posted May 4, 2007 P1170 HO2S Bank 1 Sensor 1 Circuit Fixed (Bank 1 Sensor 1) It seems it fixed something and throw a code for it perhaps it was getting fluctuating values and just decided "the hell with it" and automatically assumed a fixed value Quote Link to comment Share on other sites More sharing options...

Renboy Posted May 5, 2007 Report Share Posted May 5, 2007 Lat was correct. Change the o2 and hopefully that code will disappear. By controlled I meant, controlled. Vacuum hoses have, well...vacuum. Solenoids control the flow of vacuum, and that vacuum controls things like abv shutters, fuel pressure regulators, egr, etc. If the flow of vacuum is disturbed, by say a broken vacuum connection, then everything controlled by vacuum starts to throw codes. Now, vacuum opens the egr valve, if not close when it's supposed to be closed, then it pours co2 into the cylinders and prevents detonation, hence the egr and misfire codes. If it doesn't get to the fuel pressure regulator, then you'll end up running either lean or rich, and since it will happen on all cylinders, it will trigger fuel trim errors...as it did.

jluster05 Posted May 5, 2007 Author Report Share Posted May 5, 2007 OK...that really makes sense..so when i take it to the shop should i emphasize on the vacuum problem...or the egr? Quote Link to comment Share on other sites More sharing options...
Renboy Posted May 5, 2007 Report Share Posted May 5, 2007 Vacuum, since it's probably causing the egr problem. Quote Link to comment Share on other sites More sharing options...
jluster05 Posted May 5, 2007 Author Report Share Posted May 5, 2007 what kind of test can they administer to see if its a vak leak or should a good mechanic know from the codes being thrown from the OBD?. PS....my car was giving the EGR MAF code b4 it started throwing the vacuum leak code so which one would be the culprit to the problem?
