mattP Posted 19 hours ago Report Share Posted 19 hours ago (edited) I have a weird issue where the car will stumble and stall in D or R, but in neutral and park its perfectly fine. I had the P0456 and P1450 codes so I replaced the evap purge valve. My car has 194k miles and I find that I have to replace this valve every 80k miles or so. Anyhow, this time around I replaced the purge valve and it did NOT fix the issue. Someone had me check out the vapor canister vent valve as well, that did not fix my issue. Any ideas? My gut tells me it's fueling related because the car smells like gas when I put it in D or R. Edited 17 hours ago by 1004ron Quote Link to comment Share on other sites More sharing options...
