So you tell me that all this ( misfire, check engine and SC ) is cause by SC crank pulley ... So the mechanic who did my head didn't put it back the right way ? DEv
The crankshaft pulley is also a harmonic damper. They have rubber in them. With age they start to delaminate & cause the problems you are having. I don't think this is your mechanics fault.
If its the crank pulley failure your code will be from a boost loss fault (at least that's what I got) When mine went though I couldn't get over 2k RPM without going into limp mode. Also another possibility is that the reduction pulley on the super charger somehow worked loose and is slipping. This really depends how old your alta pulley is because they redesigned it at some point (to prevent this). A friend of mine had his pulley get loose on him before it was acting somewhat like how yours is.
Ok and a problem like that cost how much ... already cost me 5k for the head ... my mechanic change the sc oil and told me everything was looking good ... maybe he but it back with too/not enough tension ... DEv
I found someone with a OBD2 reader, will get it scan soon ... Let you know ASAP ... Hope it not a big problem ... DEv
If I remember correctly my crank pulley replacement which included the pulley and a new belt cost me around $600 I have the receipt somewhere and could give you the exact amount. most of that cost came from the price of the ATI damper.
It really depends on whats wrong. figuring that out is the first part. I know when my crank pulley went it wobbled so bad it snapped the belt. I knew the pulley was bad because I could rotate it by hand (the rubber completely separated)
I have the code !! P0302 ( P0302 Cylinder 2 Misfire Detected ) ... So i delete the check engine and scrub each connection on the coil pack ... For now no check engine and no misfire ... Maybe it was a bad connection ... DEv
When my damper went, batt light lit whenever I turned A/C on. Light off when A/C shut. I knew it was it. Glad was able to baby it home w/o popping the SES. Removed belt & checked damper w/c just fell apart in 2pcs. My options were fluid or ATI, never the OEM again. Went w/ ATI. Not a difficult install w/ all the tips on here & from Keith. It's very well made.
I also just noticed that you have the Shark Injector(?) installed. You really should consider removing it as it has been shown to cause all kinds of problems.
I know ... but people tell me to be very carefull when removing it ... if for some reason my battery loose it power it f*** everything on the ecu ... so i have to find a power supply before thinking of removing it ... I heard that Shark recommand to install MSD coilpack with cooler spark ... is it true ? DEv
Shark + MSD = Mini DEATH Please do yourself a favor and remove both as soon as you can or you will be shopping for a new car soon.
For now i only have the Shark ... If i remove it, is it better to put a MSD coilpack with my 15% SC pulley ... DEv
No....go back to OEM and simply check the #3 terminal for the occasional corrosion. The MSD pack is prone to failure. Only thing it offers is a bit of red bling.
Hope it was the real problem ... Didn't push it too much for now ... Will try it 2day, road are dry ( -5 F here ) DEv
