Well my car has been running like pure crap lately and I did a complete tune up and it still ran the same. So I decided to scan the computer for error codes and these are what it read:

Code

22 - Throttle Position Sensor Too Low
32 - EGR System Problem
34 - MAF Sensor or Circuit Too Low
42 - Electronic Spark Timing (EST) Problem
43 - ESC Module or Sensor Problem
52 - CALPACK Missing or Improperly Seated
53 - System Voltage Too High

The TPS reading was 0.58 and the IAC was 145.

I think most of you would agree that these codes probably have something to do with why my car is running like crap. Where should I start? Also, what is a CODE 52 Calpack Missing or Improperly Seated? I don't even know what a "calpack" is.

Could someone please advise me as to what steps I should take next. Thanks

 

Solve the 52, and most of the other problems might disappear. I'd suspect connections in or at the ECM first.

The CALPAK is also known as a MEMCAL. It is inside the small cover on the ECM:

 

look for a bent pin on your memcal. If you find one fix it then clear your codes and recheck.

 

so i'm guessing that having a bent or dirty connection could make the car run like absolute crap? i had the computer replaced about a year ago and it worked fine up until now. i think they used the old memcal chip and just intstalled a new ECM. i hope it still has a warranty.

 

right. If the computer doesnt see the memcal, it goes into failsafe (limp home) mode. Do you have an SES light flashing?

 

the SES light was removed because it was always on because the EGR was missing, but yes, the light is on. the car sure does run like it's in limp mode. it's limping that's for sure, lol

 

When I put my car in limp mode the SES light was just on steady, not flashing.

 

the rule myself and lot of my mechanic friends follow for older computers on cars..if you get more than 4 codes....try another computer.....

 

the car electrical place that installed the computer is closed until monday, so ill have to wait to see if this ECM still has a warranty from a year ago

 

i guess the 85 camaro's have two calpacks and my car was missing one of them. replaced it and now it runs like new. especially good after the tune-up. thanks to everyone for the help and info on the subject. keep rockin!!
