I am in dire need of help diagnosing my problems. I recently purchased a '94 z28 and have been having strange problems such as the having power when I turn the key to on but as soon as I turn the key to start it the car loses all power even when i turn the key off and back to on nothing until I shake the battery, next at random times my windshield wipers will move up like they are going to wipe but then just stutter back and forth for about 3 seconds and go back down. One night I was driving home and the check engine light came on I thought to myself that that's not good but it was late so there was nowhere to go the pull the codes so i would do it when i got home but about 5 miles later the light turned off. Then my gauges will start to freak out and say i'm going 70 when I'm standing still and the other day just got stuck at 150 until a few hours later it fixed itself, and in that same vein every once in a while they will start to flutter. Then today i was driving and gave it some gas but it wouldn't let me get over 4000 rpm it just got stuck until i let off the gas, a little while after i got into my neighborhood and was cruising along and it just died, my radio reset and it started back up as i was rolling like nothing happened.

Sorry i wrote so much I just wanted to get everything out there in case it all correlates somehow any help would be appreciated.

Thank you.

 

See this thread. It was just posted yesterday: https://www.camaroz28.com/forums/fue...-start-882697/

 

You can still pull the codes even though the SES light turned off. The code that turned it on will be stored.

 

I'll check them i didn't know that thanks.
