I just replaced my secondary coolant pump. I did have to remove the intake to get to this part. I also changed the timing belt and water pump while I had it apart. I put it all back together and it runs like total crap. It keeps running rough smells like sulfur and reads code 0300 random cylinder misfire. Any ideas?

Did you put the MAF back on properly?

No i did not do a throttle body adj. I have not checked for any boost leaks yet. I will keep looking. Thanks

boost leaks are next to check for.
