about a year ago my pinto developed an intermittent miss .. would go a week running fine then would make me worry if i was gunna make it home ..felt like a spark plug wire breaking down .. new plug wires helped for a week . miss came back . then i noticed a lot of corrosion on the dizzy cap .. new dizzy cap fixed it for a week . miss came back ..then i found the coil was loose .. tightened the coil up .. fixed it for a week .. then i remembered i have had one of the original plugs still in the engine cause i could not get it out with the engine in the car ,, i cut up my fender-well and fashioned a special tool to remove the plug .. it was perfect already ..i was not going to go into the dizzy and start replacing parts cause that was just a guessing game for me .. so i ordered a brand new dizzy on evilbay . a week later it comes in .. the fine print tells me i MUST use the accompanying special coil ... dint say that when i ordered the dizzy ( distributor ) .. so another week of waiting and the coil arrives .. amazing the difference in performance and how well my pinto would start now .. cold starting was always a problem with this car .. it`s the reason i bought the toyota 6 years ago ... anywho i went along for about two weeks happily not worried about it failing on me till it struck again ..i barely made it home ...i had been running the other dizzy on the stock pinto ignition wire which most likely was not a full 12 volts due to it being a resistance wire for the first five years it ran and it was ok .. but i learned i needed to switch my hot feed to the ignition post on the solenoid so i did .. i wrapped a wire around the ignition post and went on my way ..then my missing started .. a year ago .. yesterday i checked that wrap job i did and it was loose ..my effort to fix a problem led to a problem ,,,hence the old saying " if it aint broke ... dont fix it !!!!
