Low idle and some stalling, Misfire?

[Drakelee]

Really low idle seems like a misfire, car runs fine until it comes up to temp then

get all shaky and idle drops very low, changed plugs, wires, 2 injectors,

checked compression checked timing chains. Plan on changing o2 sensor and

coolant sensor, MAF sensor could also be the problem... anything other

suggestions?

Could be the CTS or TPS. Check em both out. Try unplugging the MAFS when the car is running and see if it runs any better or worse. If it stays the same, then the MAFS is fine.

So I pulled the mafs while the car was running and the idle evened out and it started running well then I plugged it back in and it started running like s*** again. Does the mean the mafs is shot?

replacing some sensors lets see if that works

Eeep, my bad. I worded that wrong. If unplugging doesnt do anything then the sensor would be bad, because its obviously sending no info. If the sensor is good it would run worse when you unplug it because then the ECU is not receiving the info from it. Im sorry if this caused you any trouble.

Now it really seems like a vacuum leak, after the MAFS. Think about it, the sensor is showing a certain amount of air flowing into the engine, but if theres a leak present the actual amount of air entering is less. The computer still tries to run based on what the MAFS is reading and because of this it runs worse. Look for a leak after the MAFS. Check all the vacuum lines.

I proofread this post so it is free of technical errors, lol.
