hey guys, ive got a problem with my 1993 Ford Thunderbird LX.
when i have it in park, and i just started the engine, the idle is REALLY ROUGH. like, the whole car shakes kinda rough. sometimes, its so bad that the engine just dies. now, the check engine light hasnt come on (not that it matters). if i turn on the engine, and immediatly put it in neutral, reverse, or drive, it still does it, no matter what its in. it also only happens when its starting cold, and it hasnt been running for about 12 hours.
any help on what this may be would be greatly appreciated.
^^YES I MADE THIS ON MY OWN^^
if u want one with your car in it, let me know and get me a picture of your car and how you'd like it to look.also let me know if you want to see some of my other signatures that ive done.
