Default 1993 Bonneville SSEI: Electrical Trouble under Load.

Hey i can really use some help.
Occasionally when going up a hill and i press hard on the gas my engine stutters like it is miss firing. The same when i am mid way through rpm range, and press the gas. I have changed all the cables and spark pluggs it has helped some but its still really bad. any ideas on what else it could be?

Moving this to 92-99 as this is more of a mechanical issue...

also how is the fuel pressure? and do you have any codes?

also, Take a minute and put the 93 SSEi in your sig.. This way when you ask any more questions we will know what kind of car it is so we can give you the best advice possible..

And welcome to the Club

Since you've already replaced the plugs and wires, check the coil packs. Testing requires a multimeter, and instructions are in the techinfo section.
