I have a '90 Mitsubishi mighty max with a 2.4 fuel injected 4 cyl. Engine. When I first start out in the morning the truck seems to hesitate and stammer in acceleration, but once the truck warms up for a while the hesitation goes away. I've tried changing the plugs and wires and installed a new coil. Also I have have used injector cleaners several times, but I still the have hesitation. Any suggestions where to look next?

Check to see if you have any vacuum leaks or cracked or loose vacuum hoses. If those seem to be ok you can check to see if one of your fuel injectors failing.
