Took car for inspection it passed all test at high speed. At low speed it failed hc(ppm) with a 245. Standard is 220. Changed spark plugs, pcv valve, air filter, oil and oil filter. Added guarnted to pass fuel treatment by crc to fuel tank. Ran it for a complete tank of gas refilled, drove it at high speed on interstate for 20 minutes. Went to inspection station, was taken into inspection in about 10 minutes. Everything improved except for the hc(ppm) it got worse actually was a 289 this time. So what can I do to fix this. I need this car for work and cant afford to spend much money so need the right answer first time and not mess around with suggestions from friends.
