Re: Front or back DI ?? Posted by SWEDECAR [Email] ![]() ![]() ![]() In Reply to: Re: Front or back DI ??, Ari ![]() |
I was mighty surprised when I had a V6 in with a really bad IDM and I did the swap test plus looking at my Tech 2 scanner at the same time.
To begin with the Tech 2 and related fault codes told me the rear IDM was misfiring but the front looked good.
I swapped the two and expected to see the front one behaving badly but no, The rear one still showed up as misfiring?????
I reset all fault codes and related adaptive values to see if that made a change but it didn't.
The car was still under warranty so I called the dealer up and they sent a two truck over to pick it and I didn't hear more than that they replaced both IDMs under warranty.
It might be a chance that the sparkplugs were affected and therefore kept misfiring on the same bank but I'm not sure.
To make it more difficult is that the V6 IDMs doesn't fail as often so I get very little time to do a lot of testing back and forth with different scenarios.
