I have a 98 chevy malibu 2.4L. The check engine light comes and goes, its reading P0172(fuel system rich bank 1) and P0452 (fuel tank pressure sensor condition) codes. The car dies when you idle and sometimes when you are breaking. How much would the parts cost to fix this and what are the exact parts? Ive herd people with this problem find a crack in the hose on the throttle body side and gas caps. lol. When i went to autozone, they were not very helpful and told me to google it. Any info or experience would help, thanks!
