I have a 89 900s 16v and it has been acting strange lately. I was having a problem with the idle, high in the morning (even on warm days), pulsing at idle so I changed the O2 sensor. It fixed that problem but now it is doing sometning else. The idle will not go down sometimes after the engine is warmed up, and I get a studder at about 2000 rpms if I get off the gas and let the car coast. The check engine light also started blinking yesterday, I turned the car off, back on and it stoped. The tach intermitently stops working for a while and then comes back on again. Any suggestions will be greatly appreciated. Aaron
