I got the car about 4 months ago, It had been sitting for 11 years. I got it running and a engine rod bearing knocking so I pulled the motor and replaced all of them,but I didnt rebuild b/c of money and time, but I did clean the throtle body out and the intake. So I put the motor back in and it ran fine for about 1 month then out of nowhere it will not idle at all and in order for you to start it you have to give it gas all the time or it will die and between 2 to 4000 RPM it misses. It has a used gas tank that I put in and it seemed clean and I washed it out with gas and put a new fuel pump in it and a used fuel pump relay. Can anyone tell me what they think it is.
Thanks
