Hey guys,
I wouldn't say that this is a new problem, but it is definitely a random problem that has been plaguing my rover for the past year. I guess to start off, I'll begin with a quick background story of the idle problem...
Th rover stalls out very randomly at red lights. I would say this has been happening 5% of the time. Over the past year, it went away for about 5 months. I had an issue with a dirty MAF sensor (see my other post) last week, and well, long story short, it was K&N filter oil getting on the MAF sensor. That was fixed, but now I am getting stalls more frequently. There is no black smoke, and the RPMS bounce from 0 to 750 for a few seconds, and then the engine dies. Not the same symptoms as with the MAF sensor. Before I go out and start spending money, I would some help trying to pinpoint the cause of this frustration:
1) Stepper motor has been replaced/cleaned recently
2) O2 Sensor have been replaced recently
3) "New" spark plugs have less than 30k on them
4) Again, this problem is random. After I restart the engine and idle it, it will idle normally, and would probably do so until the gas ran out. I can idle it again for 10 to 15 minutes no problem.
5) On-board diagnostic not throwing any codes
6) I have a replacement generic pump motor (Airtex) sitting in my garage that needs to be rewired to the old pump assembly. My schedule is kind of busy, and rebuilding the fuel pump is not something I can do quickly. I figure things out quickly, but I have not yet rebuilt any of the components on my rover myself.
7) I have run Seafoam through gas tank and intake recently
Sorry this post is getting long, but I just want to be as detailed as possible so there isn't any confusion. My question is, what would be the most cost effective next step? My mechanic (very good one) charges $75 for a computer diagnostic, maybe a bit more if they were to do a fuel pressure test.
I suspect the fuel pump, which has not been replaced. Does the fuel pump go t*ts up all of the sudden? Or is it a slow, painful, and humiliating death? If it was a fuel pump issue, would there be a way I could test it (ie hooking it up to an electric power source?) I'm not exactly experienced with electronics, but I know very rudimentary basics and I am a very fast learner.
If I get this persistent and random problem solved cheaply, I will forgive my rover for the past troubles it has given me. Again, I apologize for the lengthy post.
