I'm getting there!
Hey guys, I thought I woult get some input for you all on a weird issue the just started to show up. the other day I was out running around and noticed the engine was starting to miss out. it wasn't terrible, was thinking that I just need to finish replacing the injectors since I just replaced the 4 on the drivers side and haven't mustered up the courage to remove the turbo and break bolts to get the the passenger side. but as more time went by the engine was at the point it felt like a gas motor with a bad set of plug wires during acceleration, this was while I had been driving for about 2 hours. it was late at night when I got home so I left it for the next day to look at. the next morning I went out and low n behold she was running fine with no missing at all! Warmed the engine up and went out for a test run, I couldn't get the engine to act like it was again. she still has the occasional random miss or spit but not like it had been doing the night before. I felt like something electronic was getting hot and breaking down, but not sure. I checked the lift pump which I had recently replaced, it had good pressure. replaced the fuel filter for good measure and looked all over for any sign of fuel leaks on the injectors. I found one injector behind the turbo that the return hose had some slight seepage but nothing that stuck out like a sore thumb. I have already relocated the PMD away from the engine but was thinking that the PMD might be causing this. I shot the heat sink on the PMD with a temp gun after running around town for a bit and it showed 150 degrees! Mind you the engine never gets over 180. just had the radiator tank replaced so I know it's not overheating. I thought this might be a little hot but wasn't sure. It's currently zip-tied in between the brake lines from the master cylinder and the ABS motor under the hood. I know it needs to be moved out where some air can get to it better but I figured it should be in a better place than mounted down in the intake valley. What do you guys think could cause this type of missing? am I looking in the right place or are there other things I am overlooking?
Thanks in advance
