Contour Enthusiasts Group Archives Forums General Troubleshooting Starts, but won't run right....

Ok, onward from my previous post.

I made the car start - it had a hideious noise when cranking, but it started. Subsequent starts it does not make a noise. (98 SE Sport V6 ATX)

The problem is it idles at 1300 rpm. It will accelerate up to 4000 RPM, but then runs rough up to about 4500. At 4500 it acts like it hits the limiter....

I'm going to clean the throttle body and IAC, replace the fuel filter. Anyone else have any ideas?

Thanks!
Scott

That sounds like you have a clogged Catylitic Converter(s)..................check your exhaust....see if they sound right or push out a normal amount of air.........

In park, early rev limiter kicks in on ATXs. Sort of a transmission protection feature i guess. :rolleyes: Might want to check the plugs/wires as well as the hoses leading to the intake area (for leaks).

Thanks for the suggestions. I started the car when I got home and it started right up. Big Jim told me about the rev limiter, too, so I drove it around a little.

Seemed to run oddly the first little bit, but once I warmed it up ran ok.

I am still going to change the FF and clean the IAC and TB, it was just too late last night to do it.

It needs new plugs and wires so I will probably try and change those, too.

Thanks,
Scott
