Len Posted March 25, 2003 Share Posted March 25, 2003 Need some help Guys My 1983 280 ZX Turbo won't idle. Trying to cure the problem. Resoldered all splices on harness, replaced AFM, Engine temp sensor. Noticed when I looked at inside of my computer I saw some corrosion. So I replaced it with another ECU. Still no luck on curing idle (runs lean I suspect). The Serial # on my original ECU is A18-604 046 3510 Serial # on my replacement A18-60 042 2707 If you have an ECU for a Manual transmission 83 280zxt. Would you tell me the serial numbers you have? I'm thinking maybe my ECU's could be wrong. Thanks Len[/url] Quote Link to comment Share on other sites More sharing options...
Mudge Posted March 25, 2003 Share Posted March 25, 2003 Your thinking its from another year right? Mine is from an 82 automatic, so I can't help you there. Quote Link to comment Share on other sites More sharing options...
Len Posted March 26, 2003 Author Share Posted March 26, 2003 Yea, I'm just searching! Need to be a standard non-California Car. Thanks anyway. Quote Link to comment Share on other sites More sharing options...
D83ZXT Posted March 26, 2003 Share Posted March 26, 2003 83ZXT and 82ZXT ECCS numbers are A18-603 045 at least from my 2 ZXT's Donna Quote Link to comment Share on other sites More sharing options...
Mudge Posted March 26, 2003 Share Posted March 26, 2003 It would have to be pretty darn lean not to idle, usually a lean idle car would just run very weak especially going from idle to part throttle, but it should idle... Looked at the plugs? 82ZXT Automatic A18-602 043 and an ink stamping that says 2211 Quote Link to comment Share on other sites More sharing options...
Guest jt240z Posted March 26, 2003 Share Posted March 26, 2003 Any turbo ECU from 82 and 83 should work fine. Manual or auto has no impact except on RPM limitting. Idle quality will be the same for both. I have two ECU's sitting around and both checked out when I plugged them up to another car that had a manual ECU. The numbers on them are: A18-602-043 2315 and A18-602-044 2329 Quote Link to comment Share on other sites More sharing options...
Len Posted March 26, 2003 Author Share Posted March 26, 2003 Thanks for the input. Hi Donna; good to hear from you! Sounds like you bought another Z. Z's are like potato chips "bet you just can't eat just one"(or own just one!). I haven't forgot to send pictures of my car, especally now with my new 17" centerline rims & 225 45 17 Falken Azenis Sport's. Need to get her up and going to see how she drives Midge I've got a buddy who's a mechanic. I told him my car idles like crap when cold. Once it warms up idles fine. If I dissconnect engine temp sensor idles OK when cold but once warm; runs pig rich till I plug it back in! So I changed out and tested sensors as mentioned above. Then told my friend. I could just splice my engine temp sensor wire, install a reostate in cab. When cold starting: turn it one way, once she warms adjust the other way. He said NO! you are just covering up the problem, we need to find the problem! Well if I can't find the problem soon! I'm going to "cover up my problem with said reostate". I just can't be away from my baby this long! We were looking at the ECU's thinking maybe My spare ECU wasen't correct, But looks like from everyone's input. The #'s can be slightly different. Something is not telling it to richen up the mix when cold! Quote Link to comment Share on other sites More sharing options...
