I recently purchased a fairly nice '90 Civic EX 4-door. This is my first Honda, and am looking forward to it. I am not new to cars by any means, I have just been working on other makes for years, (Even got a magazine feature once!). My initial goal is to just get this thing into as good of shape as possible. I got it cheap because I was told it did not run.

After putting fresh gas in it, and changing all of the fluids, it will sometimes fire up and run great, and other times it stumbles a while before it starts. Today, it fired up and ran great, and after being fully warmed up, it did not want to accelerate at all. If you moved the gas pedal so much as 1/4", it would immediately die, but it would idle beautifully. When it would die, it would be hard to restart, but when it did, it idled great again. My first thoughts were the distributor being bad, but in my head, that doesn't make sense as to why when it was idling great, but stepping on the gas would make it die. I plan on also checking fuel pressure, and the TPS and MAP sensors as those seem like logical possible culprits to me, but I wanted to see what the Honda experts thought first, as you guys may have run into a similar problem and may know exactly what has gone wrong. Thanks in advance for any help or suggestions!

 

try fixing ur main relay near the driver side coin tray its under there just take it out and re melt and add led solder to it it should fix it also check ur injecters remove the fuel rail and pull inkecters and check if there is carbon blocking the inkecters had that happen to me or try some injecter cleaner

 

ps is ur ex auto or 5 speed if its a auto can i take lots of picks of the throttle body and tranny kick down cable i need to see somthing

 

Your main relay wouldnt allow it to idle before dying.

That is what I figured. I am also assuming that the distributor would sort of be a "go, no go" situation as well, but am not righting it off as a possibility. I am going to try and at least check fuel pressure today and see what I come up with. The car is an auto BTW.

 

check your dizzy igniter . mine acted the same way, opened the cap and look to find out the ignitor was cracked. replaced with new whole dizzy(had one laying) and ran great. hope it helps.when i pulled out my old dizzy it was seized up.

 

Finally had some time to actually go poke around on the car since I got it. Started with the basics, and started pulling spark plugs and looking at tune up stuff. When I pulled out the plugs, it appeared as though someone had gapped them using a chainsaw! After throwing in new plugs, the car runs great and this appears to have completely fixed the problem! I still have to throw on a new cap/rotor and wires because they look really bad as well, but it looks like it is good to go now! Thanks for the suggestions guys!
