Hey! So lately I was having some engine problems with my car such as stalling while driving and at idle. I went and go my spark plugs, wires, and rubber stoppers replaced in hopes that it would help but it did nothing. My mechanic then suggested a MAP sensor so I ordered one online that matched the one in my car and installed it myself. My car now drives a lot better, however my check engine light flashes when I get over 30 mph and that will not allow me to set cruise control. I am running out of money and options for car repairs. I need help!

Hi and thanks for using 2CarPros.com.

If the check engine light is flashing, most likely there is an engine misfire. You need to have the computer scanned to identify diagnostic trouble codes. Take a look through this link to see if there is anything that is helpful.

I do suggest scanning the computer so we know which cylinder is misfiring or what other problems can be attributed to. Here is a quick video showing how to scan the computer:

If possible, do that and let me know what you find.

Take care,
