Code reader and Loping problem

[Momboy007]

Hello All,
I need to purchase a code reader for my 87 2.3 FI. Where would be a good place to purchase one? Also, It seems this little truck sputters occasionally and then also lopes from time to time. It has a low RPM miss as well, when I fully floor the truck it seems to have good power with no miss, just does not want to seem to run correctly going through the gears normally.
Any help would be greatly appreciated

Rick

you don't need a code reader, go HERE and connect the jumper it mentions in the image about half way down, you don't need the volt meter (if you decide to use one it has to be an analog one) just put the jumper on and sit in the cab and turn on the key, count the flashes of the check engine light
