i checked the codes today and this is what i came up with

23 which i couldnt find what it meant so i did a search and came up with this

"Code 23 triggered the leaky injector code. Check the connections of the 23 and change it if necessary."

which makes sense cause i have code 45 as well but i dont know what 23 is i tried looking through the fsm but was lost

12-air flow meter circuit... no idea what these mean35-exaust gas temp circuit

can anyone help me out with these... my car has been shaky at idle and maybe running rich... which will probably be explained by code 45 but i bought the car a couple of weeks ago and the guy i bought it from said he had recently put new injectors in and had the reciept to show that it was done and by a "professional"

I am not sure you got the codes correctly. Without looking at the charts I think 23 is TPS. However I have a gut feeling here you were actually watching the lights flash the modes rather then the codes. When you turned the screw from the normal position the lights start to flash. 1 flash pause,2 flashes pause, 3 flashes at this point your return the screw to normal position and watch the lights they will then start flashing codes.

ok, well i did it the right way this time and luckily i got a code 55... but i still think i have a faulty sensor somewhere, sometimes my car runs great and other times it has a really low and rough idle at around 600rpm and not as much pull as usual under 2500 rpms in the higher gears as it usually does, when it runs crappy like this it usually sucks more gas, so from my researc i narrowed it down to the engine coolant temp sensor but that seems to be fine... im lost please help

Start with decarbing the intake system. I hear alot of members use sea foam product to clean it out. There are other alternatives. But I gather from the members sea foam is the best over the counter stuff you can get. In the service department I have used a couple diffrent products, by far my favorite was BG. But that is not available to the do it yourselfer. Lately though I have been using a product by valvoline that appears to do a comparable job.
