Need a little help. Keep getting a 234 code . Replaced the map sensor truck still not working right. The truck just seems to run rough. I did a search and keep seeing stuck waste gate. Where is it how easy is it to get to and how do I unstick it. I like to try to do things myself but also no when to say when. Can I do this myself. Thanks in advance

You can pull the hose off of the compressor housing and pressurize it to about 20 PSI...radiator pressure tester works great...and see if the linkage moves or not. If it doesn't move, then it's stuck.

It could either be the diaphram in the actuator housing blown out, or the shaft stuck shut inside the exhaust housing. Either way the turbo is going to have to be pulled off to fix it.
