So are you saying the car misses at idle?If so does it smooth out at higher rpm's?Also you can't afford maintenance?You really can't afford not to do that. Because if you don't then it cost's a lot more down the road sooner then later. Also do you have any code's?

Have you ever changed the fuel filter your due for a change at 100,000 mile's.I would also check your fuel pressure and have your exhaust checked for excessive back pressure.

It started losing power it would not go over fifty five mph and now it wont over thirty five mph. I checked the fuel pressure, key on it was 30 psi and dropped off instantly. I replaced the fuel pump, the pressure is back where it should be. I replaced the plugs and wires, the plugs were fouled and the wires at the coil were corroded. It drive okay cold, but as it warms up it starts surging and bogs out during acceleration. I only have a p0449 code that pops up. I attached a scanner and while running I get a cylinder misfire on Cylinders one and two.
What could be causing this?

Have you checked for a plugged catalytic converter that is what it really sounds like to me. That is the first thing I would check right now.

I think your are correct. After I posted it I drove it to warm it up so I could check the spark on cylinder two. While driving it during acceleration I heard a loud pop. It started running better. Power loss was gone I was left with an exhaust leak. I checked under the car and found the leak by the flex line. At that point I figured the catalytic converter was clogged.

Thank You

I have a 97 sl2 with error code p0302. I switched spark plug wires at the coil (#2 and #3) then get error code p0303. Would that mean the coil pack is bad?

Replace the spark plug wire. If the coil is bad you should still get a misfire on #2 the only thing you need was switch the wire and the misfire shifted to #3.

Wires and plugs were previously replaced and still have the problem. When I switched the wires at the coil, the misfire jumped to the other cylinder.
