Hi everyone. I recently replaced my spark plugs on my 98 Cirrus v6 and had to take apart the intake manifold to get to the rear plugs. I used a new gasket when I reinstalled the manifold, but now it idles at 1100rpm when the engine is fully warm. It also only happens in neutral or park, if it's in drive or reverse it will idle normally... I disconnected the throttle positon sensor and the rpms surged and then returned to 1100rpm, so it will idle at the same high rpm with or without the sensor connected. I'm a little perplexed... It only happens when it's fully warmed up and the tps connected or disconnected doesn't seem to make a difference. I tested the connector, it's getting around 4.9 volts, I also tested the actually sensor and it has resistance and the resistance changes when I move the throttle, so I'm leaning towards it being a vaccum leak?
