TBRTGP Posted September 5, 2020 Report Share Posted September 5, 2020 When i went to start my TGP this spring after sitting out the winter, it would run for 30 seconds and then shut off.. i tried swapping out the fuel pump relay fuse and it started but still has pretty erratic sounding idle.. it runs at idle at one RPM then drops runs there for a few seconds and then revs back up to the previous RPMs and continues to do that. Once the car is fully warm it evens out beter but never goes away completely. Any ideas? Quote Link to comment Share on other sites More sharing options...
Psych0matt Posted September 5, 2020 Report Share Posted September 5, 2020 LIM gaskets would be my first guess, or another vacuum leak TBRTGP 1 Quote Link to comment Share on other sites More sharing options...
digitaloutsider Posted September 6, 2020 Report Share Posted September 6, 2020 Agreeing with a vacuum leak. There are a LOT of brittle plastic vacuum lines on a 3.1 that fail over time. Check every single line and make sure there are no cracks. Especially check the one that feeds the MAP sensor. TBRTGP 1 Quote Link to comment Share on other sites More sharing options...
