My 87 Limited has a problem. When i turn the car on it's okay, but when i put in in gear it will usually sputter and die. Then i will have to re-start, put in gear and mash the gas to get it going. IAC is at 20, and the TPS is at .43. My IAC is a little dirty on the pintle location, so I cleaned it with carb cleaner. It looks a little cleaner, but didn't help. If it's not the IAC, could it be the coolant temp sensor?
