What tips or shortcuts are there? I have plenty of regular tools, but from looking at where they are, I proably need to pull the front tires and the doghouse cover. Any tips would be appreciated. According to owner (church lady I'm trying to help out) it's NEVER had a tune up! Will plugs be welded in? It's starting to not stay running after it warms up, meaning it starts and drives fine for the first leg of the trip, but after trying to start again, it starts and dies. Multiple attempts results in it finally starting, but sometimes takes 10-15 minutes of try then wait. Runs fine once it stays lit. I've had to rescue her twice, and with winter coming on, I don't want this older lady stranded.

Hi:
If the plugs have never been replaced for 187K, they do need replaced (I can't believe it still runs). They shouldn't give you any trouble removing them, but they may be really tight. Yes, you may have access through the inner fender or the dogbox.

Listen, before replacing plugs, wires, cap, and rotor, I suggest having the computer scanned for trouble codes. That way you're sure that is your problem. Also, most nationally recognized parts stores will do it for free.

Let me know if you have any other questions.

Joe
