We have a 1999 saturn sl2 1.9L car?

Question

We replaced the spark plug wires and spark plugs and when we hit the gas hard it stalls and jumps if it don't stall. It never did it before wires so we think it was not gaped right or somthing? Any idea? Other possibe problems?

Answer 1

Are the wires connected to the plugs in the correct firing order?  Sounds wrong.  Are the plugs identical in heat range and other aspects?

Answer 2

Yeah.  You mixed up the plug wires.  It fires 1-3-4-2.  1 is on the timing chain side.  The coil packs are 1 and 2, 3 and 4.  Good Luck
