Mech Posted March 11 Report Share Posted March 11 (edited) When boosting getting a really bad smell. i think the car is running too rich? Also sometimes tries to cut out hard around 4k rpms. 88 with 260k miles. All stock. Has new plugs, and injectors. Edited March 11 by Mech Link to comment Share on other sites More sharing options...
psu_Crash Posted March 15 Report Share Posted March 15 (edited) The cut out could very well be a leaking vacuum advance. Really bad smell of fuel? What do the plugs look like? Edited March 15 by psu_Crash Link to comment Share on other sites More sharing options...
TexasQuest Posted March 15 Report Share Posted March 15 The only way to know for sure if the car is running too rich is installing a wideband 02 sensor. Link to comment Share on other sites More sharing options...

FieroGTFan Posted March 21 Report Share Posted March 21 My car used to have a really bad fuel smell under boost that took me a while to figure out. After going over everything it ended up being the throttle shaft seals for me. But that doesn't answer why it is cutting out at 4k RPM. Link to comment Share on other sites More sharing options...
