intermittent starting problem
im having a starting problem with my 1993 3kgt sl NA. if i go out on a cold morning or when the car has been sitting for a while it will start right. if i let it idle by itself it will just cut out completely and die. no hestitation or sputtering just die. when you go to start it up after that it wont start it will turn over fine but no start. if you come back like 15 minutes of letting it rest it will start right back up again. so lately i have been holding it to 2k till it warms up and then just drive it till it gets to full operating temp and its fine. runs perfect. like nothings wrong. no cel light. but if you shut it off and try to start to it back up like 5 mins later it wont start. same thing. not even an attempt. so as i was trying to track down the problem and i took out the iac cleaned it up. no change, but was really dirty but i knocked on the mafs and it immediatly either made the rpms drop or shut off the car completely . but i havent been able to start the car by knockin on it when cranking. not sure if the mas could make it not start. it doesnt smell rich or feel rich when its running normal. i wanted to see what you guys think. btw i dont have a datalogger or any a/f gauges or anything. would it be worth getting one
