2002 clk430 check engine/multiple emission codes
Have several things that come up, replaced a couple and items still come up , check engine light goes on and 9 codes come up.
4- 02 sensors & egr, which I just replaced.. and still get codes, also sec air inj sys,evap emiss purge control valve circ open , evap emiss sys vent control,sec air switch valve,sec air inj sys.
Purchased in Nov with engine light on, only 88k when bought now 89.5 , runs great, great acceleration, gets 25.5 hwy doing 70-75. Was rebuilt title from 06,previous owner purchased in 09 passed emissions 3 times.
Have looked thru the posts and did not see anything that related to multiple codes I have. Am going to go thru and check all connectors and ground terminals. Hope that previous owner did not boost jump which could have fried a control/computer. The stereo worked fine for a few weeks then the amp fried,swapped one from a e320 and works fine..
Whatever anyone can input would be greatly appreciated, and if anyone is a MCB tech on the side in CT/W.Mass I would certainly have you do some work on it if interested.. Thanks Have a great weekend
