I tried searching your DIY section but couldn't find that post on how to replace the check engine bulb. I found the post on how to remove the cluster gauge though. My 1999 Acura CL went to emissions and failed. It had several check engine codes. I didn't know it because the bulb had gone out. Now I need to replace the bulb so I can fix the problems with the car. I need to know how I go about removing the bulb. Do I remove the plexi glass in front of the gauge or are the bulbs readily available in the back of the cluster? Any help would be greatly appreciated. Oh, by the way first time here. Looks like a great forum. Thanks!
