#38 of 47 rough running 03 cav 2.2 by caveman55

Jun 25, 2010 (5:15 pm)

Im working on an 03 cavalier with a 2.2 ecotec. It idles and runs rough at any speed. Codes were 171 bank 1 lean, 108 map hi input 128 coolant temp not in spec and random misfire. Map was replaced, new plugs, new coil unit. TPS seems to be ok. Pulled the new plugs and they are black seems rich to me not lean. All cylinders are at 205. Any suggestions where to look.
 
Thanks

My abs light just came on all of a sudden and i had the brakes done a few months ago and the fluid level is full. Anyone know why it would do that?

I know you posted this a while ago but did you figure out what was wrong with it? My cav is doing the same thing and I don't know what it is. If you do and you could let me know that would be great. Thank you.

I found excessive slack in the timing chain and it had jumped a couple of teeth. The timing chain guides were also broken. Check the timing chain ASAP because you can mess up the valves and you'll have to rebuild the head.
 
Good luck

have 05 simliar trouble, replaced tps, plugs, crank sensor, coil packs etc, just kept throwing money at it, Found out that cavaliers are real sensative to poor grounds..the cable from battery (ground) down to the battery tray was not making a good connection at the tray (body ground) was very rusty, replaced it, the same
cable goes to the right side of the engine (stud sticking out of engine block) also the 2 wires from the main harness also hook to this stud, they were corrected a little, snipped them off put ona new connector and HOLY CRAP this car never ran this good, no propblems or lights on since.

so i have 1998 chevy cavalier, the problem is when the weather its cold, when i turn on my car it won't start, so i decided to just turn to run position. And after a while (depend how cold the weather is, sometime it took 10minute,somtime 30minute,sometime 1hour, sometime i need to wait for the sun to sunrise first) then the all lights on the dashboard will on (they are blinking for a while, and needle it was like shaking). So after all the light on, and completely stop blinking, i start to turn on the engine. But it won't start, because the THEFT system light is blinking. And i wait about 10 minute, then the THEFT SYSTEM lights stop blinking. on that time it will start right away. But it's totally diffrent if the weather is warm. if the weather was warm, i just turn on to run position and all the lights on right away and i just turn on the engine and its working. I already change the iginition key for 200$ and 40$ for ignition starter switch . But i still have this problem. PLease kinda help me to fix this problem. i do really appreciated it.
