  1. 2 codes....p0106 Map sensor performance. p0386 Crank sensor B A decel stall would be more likely a MAP issue than a crank sensor. Here is the MAP info... The manifold absolute pressure (MAP) sensor responds to changes in intake manifold pressure. The PCM supplies a 5 volt reference and a ground for the MAP sensor. The MAP sensor provides a signal to the PCM relative to the pressure changes in the manifold. With low manifold absolute pressure (high vacuum such as during idle or deceleration), the PCM should detect a low MAP sensor signal voltage. With high manifold absolute pressure (low vacuum such as key ON, engine OFF or wide-open throttle), the PCM should detect a high MAP sensor signal voltage. The PCM tests the MAP sensor to ensure that the sensor is functioning properly. The PCM predicts a MAP sensor value based on throttle position and engine speed. The PCM then compares the predicted value to the actual MAP sensor input. DTC P0106 will set if the actual MAP sensor input does not closely match the predicted value.
  2. Aftermarket ones almost always can be used on either side. Thats not always the case with OEM ones. Not so much the strut itself but the welded on brackets can be different from side to side. I would double check before having one shipped.
  3. Looks like there are still a few around. That said...I think you need the right one....this part # may be for the left side. http://www.ebay.com/itm/Cadillac-GM-OEM-03-04-Seville-Front-Suspension-Strut-19300076/171906775427?_trksid=p2045573.c100033.m2042&_trkparms=aid%3D111001%26algo%3DREC.SEED%26ao%3D1%26asc%3D20131017132637%26meid%3Deaf49626e0ad4d4c82b3b56c1729b23e%26pid%3D100033%26rk%3D1%26rkt%3D8%26sd%3D171906775427
  4. I think they are still in the sunroof business.....have you tried contacting them? https://www.webasto.com/us/markets-products/car/ You also might be able to find the service manual for it online. Do you have the model #? Here is the 300 series.. http://www.donmar.com/tech/h300l-svcmanual.pdf
  5. The data line is actually tan on the 1994. Circuit 800. There is suppose to be a cover on the ALDL. It has a little jumper in it to complete the loop....is the cover there? The system should still work if the cover is missing and everything is ok. But if there is a problem...the cover works as a redundant connection.
  6. Thinking about the IPC.....there are some differences. The 1992 one was a one year configuration. Others....the red line is different on the tach depending if it's a 4.9L or Northstar. The mileage is stored in the IPC. So a used IPC will show a different mileage. That can be fixed at a Delco speedo /radio repair shop for some $. Likely some settings would have to be changed in the IPC...that's doable. The PCM.....cheapest thing to do is drop it down and tap test it. Any scrambled data...stalling...any glitches while car is running and tapping would make the PCM suspect. Plus they are kinda cheap...around $100 for a reman unit.
  7. Take a close look at the sockets before spending too much time. Cadillacs of that era could have bad grounds inside the socket plastic. See burn mark in plastic in socket on right. The fix is to splice on a new socket.
  8. Yes....the IPC is the instrument panel cluster. There are other years that should work....key word being should. Kinda rusty on the details of the IPC. Basically all the computers are tied together on a big loop so they can transmit data to other computers and the IPC. Works great until one of the computers goes bad and pulls down the data on the 800 circuit. Then all kinds of crazy stuff goes on. Your lucky if yours is doing it on a regular basis. Intermittent ones are very difficult to pin point.
  9. Hmmm......The IPCs can also go bad and display these problems. False messages...and '---' in the data display. Some kind of problem on the network data 800 circuit. Can be a bad computer on the 800 circuit that corrupts the vehicle data.
  10. Couple of clues... IO34 code is 'Loss of PCM data' I also think you are also getting '--' in the data displays. No IO54 listed in my 1994 service manual. Are you sure that is the correct code? Maybe IO52? Being the trans is shifting funny too.....my guess is the PCM is going bad. It is mounted behind the glove box. You can drop it down and tap on it some while the car is running....any glitches or stalling while tapping will confirm a bad PCM. There is also a TSB about some bad PCMs for 1994 models.
  11. It's a wonder sometimes how cars can run.. How long have you owned the car? That sure doesn't look like a 25 year old coil.
  12. The ST-125 is a spark tester for HEI ignitions. Not really a spark plug tester. If the spark can't jump the gap...from the center to the outer edge...it's too weak. You should be able to easily hear the spark snapping from the drivers seat while using one for testing.
  13. My GM manuals don't go back that far.. Both injectors need to be pulsing...I think the ECM needs the ignition module to pulse the injectors.....so the pick up coil and IC module sound ok. Have you tried replacing the coil on top of the the distributor cap? Or maybe bad rotor or cap.
  14. I doubt it.... There was at one time a cottage industry fixing sagging GM headliners. They would come and redo it in your driveway....kind of like PDR. Results were like brand new. You clean and scrape all the old material off the backing board. The foam backed fabric material is available in different colors....that and 3M spray. Search on Google for 'fix sagging GM headliner'. There may still be shops that fix them....maybe under $100. This assumes the backing board is still ok.....also new headliners can now make the visors look ratty. Youtube video...
  15. Last fall....had a suspect navigation radio in wifes 2012 Equinox. Radio would turn on/off at random....loss of song title and station data....outside temp etc. I would also loose the HVAC panel and lighting as that is controlled by the radio. Sent the radio unit in for repair. Way cheaper than a new unit. About $400. Everything has been working fine since then. Anyway...place I used was.. http://www.radiosandmore.com
