So I was changing out an A/C Line that broke. In order to do that I had to take my AEM CAI off to get to the line. When putting the Intake back on my friend and I decided to cut it in half to make a short ram. It rains to much around here and floods really easy. Anyway I put the new A/C line back in and the intake and hooked everything back up. When I went to turn the car on, it started up alittle rough but idles fine. It has the check engine light on. I did the paper clip trick and figured it was code 3. For my MAP sensor. I looked at the sensor and the wires had been pulled out alittle from the clip. I fixed the wires to the wire diagram I got in a Haines manual but the code is still throwing. I've disconnected the battery to try the reset trick and it is still throwing the code. It's still rough to start up but it drives ok, just in safe mode. Dumping alot of fuel into the system. Could the whole MAP sensor of gone out right at that moment? Also I pulled the battery before working on the car so I don't think it shorted out

 

Did you unhook and possibly get the MAP and TPS sensors hooked up backwards?

 

Try pulling the backup radio fuse for 30sec to reset the ecu, then see if it's better.

 

You are going to need to back probe the correct wire on the MAP and give the throttle a few different positions with the engine running and monitor the voltage changes going back to the computer then compare the readings against a MAP / RPM chart in the repair manual. It sounds like you have a vacuum leak from the maintenance that you did, spray some expensive carb cleaner around the intake gaskets and see if you can tell the difference with the idle if you hit the leak with the carb cleaner.

 

Ok thanks for everything hopefully I can figure it out.
