Ok so I just did an oil change and filter. Plus new platinum plugged and new coil wires. I was at the end of a 7 hour road trip and the motor started to loss power.I pulled over and it died. When I restarted it, it sounded like it was missing really bad and idling rough but once it gets up to 5000 rpms it seemed tof run better till the rpms drop again. What do you think the problem is? Apex seal maybe?

 

Sorry the car is a 86 gxl 13b stock.

 

welcome to the board.

what kind of plugs were these platinum plugs you mentioned?

 

I don't remember what brand. They were the more expensive ones at orillys auto parts.

 

As an advocate of the Search function the first research you should look into is how to Compression check the engine.
This will tell you if the engine has given up and save you a lot of tinkering with other stuff that may not even help.
