Auto Computer Exchange One after another of junk yard dirty PCM from auto computer exhange Tampa, Florida

I am a general mechanic that knows a thing or two about engines and all related componets. I rebuilt my Jeep 4.0 with little problems only to find the worst was about to come.

I have heard leaving a computer( PCM) goes out if left uncharged and when plugging back in after a period time or if any short was to happen. From what I remember I didn t have any. The problem I had was with my timing.

I was troubleshooting over and over trying to find a short but could not find anything. I got to the point I just ordered a computer from auto computer exchange for 199.99. Hey better then 800.00 for a new one. Recieved the PCM and had the same problem but I got a few other codes with it. Returned it received the second PCM from auto computer exchange and low and behold still nothing but the same problem as the first they sent me so I just return that one also. I called them everytime I keep telling them what the problem is with my ignition advance and I see it on my brick scanner. They told me to clean the points one the connections from the plug and computer must be greasy. That should fix the problem but in the mean time they will send out the third. Received it no luck. I took it to a well known dealer to diagonse it and they said they had to send back 5 computers before they got the right one that worked when they dealed with auto computer exchange. I guess I have two more tries. When they found what was wrong was the PCM. The third one they sent me was still wrong. Called again told them I had it checked by a dealer and they said clean the points again they are really dirty should cause problems like that I was describing. They said send us the orginal and the replacement. Who would ever send the orginal. Received the forth one still nothing. I returned that also. Everytime I received a computer it hardly looked dusted off other then to slap a new sticker on it. After I recieved the forth PCM nothing. It won t even start. They won't refund my money but told me to send the orginal in yeah right. If I had the last one they sent me I could at least use it as a boat anchor. But I have the same as what I started with but $200.00 less and 4 months of it not working. Ripoff Straight scam selling junkyard parts.
