My mechanic gave me the following codes that he got from my car.
-1598 A/C pressure volts too high
-204 Injector # 4 control circuit
-0113 Intake temp volt high
-0340 No cam signal at PCM
-0123 TPS volt high

I tried researching these with no luck. I was wondering if someone could help me out here. Now also, the engine light does not always come on. There will be days where im driving and then it comes on, and the car shakes etc.. there will be days where it misfires right away on start up, and shakes but when i drive for a while the shaking stops and the car runs smooth even with the engine light on... and finally, I will go days with no problems at all, no engine light, nothing. Sounds like maybe some loose wires or something?

With any of the codes listed above, will that cause my car to stall? Because it hasn't stalled yet on me, but I am curious.

Thank you

 

update on this. i tried the ignition self check, and i counted the flashes etc.. and i only got 3 codes
12-Direct battery input to PCM was disconnected within the last 50 key-on cycles
27-Injector control circuit
33-A/C clutch relay circuit (question about this, my A/C is broken and does not work, so if i disconnect it, will that code go away?)

looks like my mechanic is trying to screw me, which ive heard he has to many customers.

 

so no one is able to help clarify any of this for me?

 

It sounds more like the car is misfiring ... When was the last time you replaced plugs, rotor, and cap ????

 

plugs and cables are brand new. and i dont know if the rotor and cap come with the distributor, but thats fairly new as well.
When we looked further into it, it was cylinder # 4 and it was a fuel injector problem. could a injector problem cause misfires as well?

 

yes
