So a couple weeks ago my 2006 Xterra (manual, offroad, 130k miles) began to randomly die on me while driving. There doesn't seem to be any rhyme or reason to it happening, but about every other time I drove it it would at some point start struggling, then just die.
Once it did die, it would have a hard time starting up again. It would crank just fine (battery is new and appears in good condition), but would just rumble for 10 seconds or so after cranking (pressing the gas wouldn't rev, but would eventually kill it) and then die. After enough tries, it would eventually rev and I could go on my merry way only to have the same thing happen a couple days later.
I took it into the shop where they couldn't reproduce the problem (not surprising since it doesn't happen every time I drive) or find any obvious issues with the vehicle. The check engine light did come on after dying at one point just before I took it in and they said the code read P0430 (Catalyst System Efficiency Below Threshold (Bank 2)). They also said the converters didn't look to be in bad condition and didn't recommend replacing them yet. The only thing the shop did was clean some corrosion from the battery cables/terminals.
Unfortunately, the problem cropped up again today a few days after getting the Xterra back from the shop. I should note that the whole problem started happening very soon after I changed the oil and ran some seafoam through the vacuum line / tank / oil. Not sure if it's related, but figured I should mention it.
Any ideas on what the issue could be and how to go about fixing it?
Let me know if you need any more info to help troubleshoot.
Thanks!
