1998 ML3rry puxkwr20 Engine Swap
I have aswell performed a 98 ml320 engine swap.
After performing the swap has anybody else had any limp mode issues? I do. What I've done so far is replace conductor plate, and tcu that i got out from the same 99ml320 I got the newer engine from.
Result: no longer slipping at first acceleration from a stop but still appear to be unable to reach higher gears( feels like 3rd,4th, 5th) and shifts occur in my opinion at a much higher rpm(4,5)and don't seem when in drive to ever really drop to 1or 2 rpms. However in park or drive when at complete stop the idle is perfect. I bought the trans dip stick to have a adequate reading of my atf level and I'm certain I'm good. Any suggestions?
Here is the other explanation for what I might have mentioned earlier if not first of all is that I have this to much of a coincidental misfire on 4,5,6 cyclinders which are all on the same side leaving me to believe that something sensor or ground re lated is re sponsible. But which one or where and how ? If any one has some input I'd appreciate it. Please do not respond with ?'s just suggestions and/or ideas. Thanks
