Here ya go. Check coils and try 12v ecu mod.
And please use 91 dude, its only 4 more bucks per fill up. Only 2 more bucks if you do a a quick $25 gas stop. A lot of guys on here have even said the 87 wastes a lot faster too so youre spending less...to get less lol. Idk though have never used regular.
Good luck!

There have been so many issues and threads like this one recently and most of them ended up being the coils. That's where I would start. Unplug each coil one at a time and attempt to start the car. If the car doesn't start with one unplugged it means that coil is good.

yeah those coils are a pain. Even if the unplug a coil option doesn't show you a result (like mine didn't) try replacing them. For some reason our coils go bad if shaken bad or any kind of short in the system. I put 30k on my car since December and have replaced three coils (yes I know there is only 2 on the car). Generally the driver side one goes first as it is lower and closer to water/fluids.
