RPM needs to be about 1000

Get new spark plug cables and change them but only one at a time so the firing order does not get mixed up.

Hello lysiphlebus2,

((My thoughts: cold START valve IAC at very bottom))

Plenty of places will do FREE diagnostic code reads.

I would rather suggest it be a muffler shop than
AUTOZONE... but either is better than guessing.

AUTOZONE will likely make you buy OXYGEN
sensors... (but that makes about as much sense as
buying a new THERMOMETER every-time you
have a FEVER.

What you are describing sounds (from an old
mechanic's perspective) like a collapsing
catalytic convertor or rotted muffler baffle
(a slightly better blockage will halt operation
completely)...

((again speculation... get your codes read))...

Do not buy OXYGEN SENSORS....

Know your prices before waltzing into any
exhaust shop.

Try a crank sensor next. They get hot and stop working.

You need to drain some coolant. Loosen and disconnect water lines by the firewall- the ones in the way of your wire change. u need to get a diagram of the firing order of the engine so that those wires are correctly connected to the coil packs.

Hi Raynellmarti. Here is the image of the firing order on a 3.1L Buick that c17hydro was trying to post for you. He encountered an issue uploading them, and sent them to me so that I could try and post them.

Check the feul pump relay or the Fuel Pump resistor.
