i just bought an 89 le from an auction and i'm trying to get it up and running. at first it was stalling out whenever i took my foot off the gas. i thought it was a fuel flow problem because the car had been sitting so long so i changed the fuel pump & filter. i ran the codes and it gave me the following: 14 - coolant temp sensor, 24 - vehicle speed sensor, 42 - electronic timing spark. i changed the CTS (code 14 the cheapest one) and now it idles at 1700 rpm and the speedometer stopped working (and code 14 came back).
i'm not really what you would call the machanic type and i don't wnat to start spending a fortune just buying parts. does anyone have any suggestions on what I should do next???
