i have an 87 4runner with a 92 22re engine, ive had the combo for about three monthsso far and i had the motor in the original truck for alittle over a year last year and never had an issue, early today i moved it and it ran fine, i started to install some airhorns than i had to move so someone can get out of the driveway, and when i went to pull back in, and it started to run like it had a miss, i did some simple checks and i had spark at at all cylinders. i have no idea what to do or what could be wrong, so if someone has any advice it would be much apreciated.
