Replaced CPS, check engine light still ON!
OK this is quite odd, but let me explain. Car died in middle of the day about 4 weeks ago, MB roadside came out with gas, tech diagnosed problem as CPS. I went online to autohausaz.com and bought a CPS, replaced. easy enough. car drove FINE for about 4 days, i let it sit the 5th day. 6th day, i start driving it and i get about 5 min away from my house and boom check engine light, sluggish and wont accelerate. car doesnt die though but it seems like it would. what the heck is wrong now? MAF? im at a loss, im about to go plug in OBDII reader to check codes, but could it be another bad CPS?
OK EDIT:
just plugged in code reader; codes:
P0335
P0305
P0300 PD (pending code, meaning code has not matured)
P0302
Could the CPS cause misfires?

From what I understand the CPS does not throw a code. The code you are getting is from another component. Have it correctly diagnosed, thats the only way to find out.
