The car starts and runs fine. Then after it warms up when I get to a light the idle is rough and will stall if I don't shift into neutral and keep the idle up. Then when I start driving again the power is really low but eventually gets better.

Any ideas where to start? From what I've read it sounds like it may be fuel lines/filters/manual pump leaks. Just though I'd ask before I started digging around in case anyone had any ideas.

Valve clearances should be checked. Especially if you have no ideal when last done. Maintenance requirement every 15K to check them.

May not be it but a place to start.

It was a clogged filter. Big piece of whale snot. Seems fine now.

Have you flushed/cleaned your fuel tank?
May help some of the whale snot issues

PO claims to have done it and I tend to agree since it ran fine up until then. Might be some bad fuel.

I was planning on replacing the sending unit this winter so I'll take a look then.

We occasionally forget almost always fuel filters first on any suspected running problem. They can enable so many issues .

I did this time.

Yeah I'm new to this whole thing. Why do you think it only happened after driving 30 minutes or so? Just bad luck?
