Ok, well to start this off I have a few problems, but lets tackle them 1 at a time. I refuse to throw money and parts at the problem, but I am willing to do some diagnostic stuff and figure it out. so, i wanna run what Ive come to assume by you guys first to see what you think. Its an 88 v6 5spd with 120k miles and probably all original parts aside from basic maintenance stuff. It has had a good tune up.
I am getting absolutly NO engine codes.
1. I have a small exhaust leak AND a plugged cat. I know this because i have a low thumping noise comming from a muffled exhaust sound, and the headers glow after idling for just a short bit of time. I am just goign to cut it out and put a straight piece of pipe in for now until I am ready to run headers back.
2. I have a high idle. The previous owner told me he thought it was from a vacuum leak around the EGR tube. The car idles around 2400 rpms. it will go down to around 16-1800 after it warms up, but its still way too high. I also think im running a little rich which would kinda fall in line with this.
3. I also think the fuel pump may be going out. (I thought typically that when a pump goes out, it goes out, but I could be wrong) I am getting this horrible moaning coming from it seems right below the center console sad excuse for a glove box. The noise comes and goes, typically at lower rpms, but is not consistent with the engine speed. The noise is barely noticable outside the car, but inside it is very loud. I even tried opening the hood/decklid to see if that gave any hint as to where it is coming from, but it didnt. The voltmeter also takes a little hit when the noise starts.
The car also stalled today at a light. it fired right back up, but It was something I definitly was not expecting especially considering the high idle.
4. I am getting my volts light lighting up. well it flickers. I think the alternator is gogin bad, its not low volts, but high. I've seen it spike up to the 18 mark. It also did rain today if that makes a difference to anyone.
These are the first few problems that I am having, If anyone has any opinions on what Ive said (agree, disagree, unsure about my diagnosis, please let me know.) I not only refuse to throw money at the problem, I cannot afford to throw money at the problem, Although I will spend money to get it fixed if thats what it needs. Thanks
