My car is missing bad, the check engine light comes on when im driving it but I cannot get the codes but I have the key to retrieve the codes just don't know what blinks do I write down.

SOURCE: i have a '06 chevy aveo that won't hardly pull

have 'sort of' the same [problem on wifes car. it lost power while driving and she had to pull over and shut the car off and restart it.
I pulled the codes with a OBD2 scanner and came up with 3 codes, P2106, P2110 and P2135.
Last one is for Throttle/Pedal Position Sensor/switch A/B voltage Correlation, figure that must be the TPS as its known. Checked on line for it and found several for around, get this, 181 dollars!!!!
Other codes were for Throttle Acuator Control System Forced Limited RPM.
So I'm figuring a new TPS "might" fix the problem but $180 is not easy to let go of but may have to.

First, do as first post says, or take it to a Checker or AutoZone or someone like that in your area and have them run the OBD2 scanner on it to see what codes your car throws, then you have an "idea" of what may be wrong, sometimes those codes will not send you to the correct area. Just replacing sensors can get expensive only to find out it is caused by a vacuum leak or throttle body is bad (those are real pricey).
Check with someone that get retrieve the codes for free first.

Now change the distributor. Get one from salvage or e-bay. Did the timing belt jumped a tooth or is it new. Vitally

SOURCE: hold light blinking, check engine light on, engine slows down

check tps sensor (throttle position sensor in backside of the throttle cable) and map sensor (manifold absolute pressure on front little 1 inch sensor with vacuum line) make sure there plugged in. the ecm (engine control module driver side inner fender) and tcm (transmission control module under dash) both need the data to know when to upshift and increase fuel/air. Otherwise the computer runs default values and guesses off of other sensors giving poor performance. also disconnect battery for 15 min. usually resets aveo service lights if you dont have a scanner.

You'll need to find out what code you have. There are lots of differant things that can cause a check engine light or a truck to run poorly.
For what it's worth sounds like a vaccume leak, maybe the egr. But you need to find out what the code if first!

SOURCE: service engine soon light blinking /car backfiring and missing

If your check engine light is blinking, you can take your car to Autozone, Advanced Auto or other parts house and ask them to get the engine codes. This ios a FREE service. It sounds like your camshaft positioning sensor, Cam Positioning sensor is bad. This is how comuterized systems tell where the cam and crackshaft are to set the timing. It sounds like you have timing issues.
