Car is missing and has no power especially when climbing a hill. Can this be bad coil pack
Possible but not probable
indications are injector fault, injector wiring fault, ECM fault or mechanical fault
run the fault codes to get closer to the fault

Misses that occur only under load are typically spark related. Engines typically need about 8000 to 12000 volts of spark energy to idle, but under load and acceleration, they can require as many as 30,000 volts. Weak coils frquently can still make 10-15000 volts, enough for light cruising and idling, but insufficient for load. Further, a defective boot or carbon tracked sprak plug may fire normally at idle and cruise, but "arc" down a black carbon track in the plug porcelin under load. You should take the car to someone who has the equipment to propely examine misfires. Or if you really feel the need to do it yourself, you could try pulling all spark plugs one at a time( assuming you dont have a scantool or trouble code data to point you to a specific cylinder) and visually inspecting them. They should ALL be clean and dry and white all around. If you see any black lines or marks in the porcelin of any spark plug, replace both that plug, and the wire or coil boot attatched to it. If you dont see any dirty or wet or oil soaked plugs, you likely have a weak coil that will require scan, scope, or load testing to isolate. Most professional shops have the equipment to do this.

Go to Google... Then exemple type download Chev impala 1989 Wiring diagram ... Sample is that... Good Luck

You could have a dirty fuel injector.Just add some fuel injector cleaner into the fuel tank.Try not to get some cheap stuff.You can have the code checked to see what code is making the light come on.It could be a certain cylinder that is causing the problem and the code could help in finding what cylinder it is.Let me know if you need more help.Good luck.

check spark plug gaps -25th- if wide this will cause the miss ,if they are ok or still the same even after re-gapping then its a coil pack but what one ?? they are not cheap and no a code reader will tell you this information what you need is a induction sensed meter like either a nice snap on timing light if they still exist or a automotive multi test meter .
