Make sure all of your lines are secure and ziptie or clamp down ones that feel loose. Get the codes read ASAP. Razz1 03-17-2009, 02:50 PM I believe this cell RKEP0039 has been determined to be nothing. Search the ECU tunning threads. P0300 is random misfire. One of the causes is a leak on the intake. Recheck and tighten the install. Also, clean the MAF. laythor 03-17-2009, 03:22 PM Cleaning the MAF should be something everyone does at least once a year. quillero20 03-18-2009, 09:21 AM thank to everyone who replay to my post, i'm going to check that about the leak and also cleaning the maf sensor again but also i have pulleys and i forgot to mentioned them before but i really don't think this is the problem i really think it could be the cold air so i'm going to check that, thank you REV-N-HIGH 03-23-2009, 08:56 PM I also installed a Mazda Speed cold air, I had to get it tuned in order for the light to go off. teknics 03-23-2009, 09:05 PM I also installed a Mazda Speed cold air, I had to get it tuned in order for the light to go off. what code did you have? kevin.

Did you remember to cap the VFAD nipple on the intake manifold extension? laythor 03-23-2009, 09:36 PM I also installed a Mazda Speed cold air, I had to get it tuned in order for the light to go off. tuned how? kdparsons80 03-23-2009, 10:12 PM I have the MS CAI i had a similar problem. I capped the wrong vacuum line. Make SURE that you got the right one on the manifold. The directions are a little vague on that step. nycgps 03-23-2009, 11:12 PM I also installed a Mazda Speed cold air, I had to get it tuned in order for the light to go off. rofl ? Tuned ? My car must be smoking then. cuz I just install mine, and no CEL ever? quillero20 03-24-2009, 10:37 AM yea i took it to the techs and they said that my problem is the underdriven pulleys so i need to het my car tune..... so guys cold air intake if you don;t put it right like they said tap the wrong vacum or tip it'll get you the code... teknics 03-24-2009, 12:44 PM yea i took it to the techs and they said that my problem is the underdriven pulleys so i need to het my car tune..... so guys cold air intake if you don;t put it right like they said tap the wrong vacum or tip it'll get you the code... underdrive pulleys require tuning? thats wrong too. if you changed your crank pulley do the NVRAM Reset procedure that may help. a CAI and underdrive pulleys wont set off a CEL requiring a tune in almost any car i could think of. kevin. nycgps 03-24-2009, 03:40 PM yea i took it to the techs and they said that my problem is the underdriven pulleys so i need to het my car tune..... so guys cold air intake if you don;t put it right like they said tap the wrong vacum or tip it'll get you the code... Unless the installer is an idiot. there is NO WAY that they can install the MS CAI wrong ... So easy even caveman can do it ... Pulley needs a tune ? ... hmm ... ok ... nope ... teknics 03-24-2009, 10:01 PM Unless the installer is an idiot. there is NO WAY that they can install the MS CAI wrong ... So easy even caveman can do it ... Pulley needs a tune ? ... hmm ... ok ... nope ... if you dont put the screen in you can get lean codes, had that happen after installing a motor, apparently when i took the CAI apart the screen turned sideways and wedged in the tube lol. kevin. quillero20 03-25-2009, 09:37 AM don't know but i'm going to get the second opinion |
