Dodge Repair Questions? Ask a Mechanic for Answers ASAP
hi i'm bill
sounds like you may have an oxygen sensor going bad and giving the computer a false lean signal this will drive the computer rich,also a bad egr valve (if it has one, some did some didn't) can cause this, code 43 is an invalid code so i must assume you tried to cycle the key to get it in 96 and for a few years th ekey cycle method of retriving codes was discontinued BUT the computer would still flash out a code this was for engineering not for us in the field, proper codes are retrieved with a code reader and will be a "P" code (Pxxx)
if you can get any "p" codes for me i can better assist you if you don't have a scanner most autoparts stores can retrive them for you like autozone or advance i strongly suspect the oxygen sensor the egr will cause issues when cold and warm USUALLY the oxygen sensor comes into play after it warms up some remember "garbage in garbage out"
i am going offline for the night(geting late here in the east) i will reply tommorrow morning if needed
I have erased the codes. I will have to drive until the codes appear. I will the get the codes read and post.
You might be able to help with a cavalier fuel enabel code p1629.
No problem. I still have to get the codes read on the neon will get them later today.
I connected the noid on each injector connection and they all flashed. I pulled the fuel rail and the injectors they all appeared to be normal. Number four was a little dirtier that the rest. I cleaned with carb cleaner and reinstalled the injectors. I drove the car for about one hour and the car did not miss at all. I think that one of the injectors must not have been seated properly and had a vacuum leak. My son is going to run the car home about 45 miles. He is to let me know how it runs. I cleared the cel and hope that it does not return. If it does I think that I may have to change the injectors. I also put Lucas injector cleaner in the gas tank.
I appreciate your help on this I was definatly going in the wrong direction. I will keep this open for a week in case I still need help and the problem reoccures.
Thanks Again greatly appreciated you are a godsend.
