So I've searched for this a couple times and can't seem to find the answer I'm looking for.

Does anyone know the dimensions for the bolts that hold the factory skid plate to a 2001 4runner? (the one directly under the engine).

Also, I'm going to be hauling a 3,500lbs load approximately 1,100 miles in the next week. Before I do this I am do for an oil change so I'm just gonna go ahead and do that and tranny/diff fluids as well. Anything else I should maybe do to prepare for a long trip like that.

On a seperate note, I have had a CEL for a misfire in cyl 3 for about two weeks now. I cleaned my MAF and throttle body real good, replaced my spark plugs and cleaned my air filter; reset the computer and yesterday it (CEL) came back on. A buddy of mine was saying it may be one of my 02 sensors going bad, just curious if anyone has any insight as well. **The truck doesn't seem to have a misfire all the time, I think it's only when the truck first starts up once in a blue moon.**

Any help would be appreciated, thanks in advance.

bolts are an M8 x 1.25 x 15mm (length is a guess but would work)

As for the misfire search the site a bit and you'll find a lot of troubleshooting suggestions

Thanks for the response, I'll have to find out the length of those later on I guess.

I did however, go down and get the code(s) ran again and it seems as though I've got a p0446 which is EVAP short circuit. I can deal with that and it's multitude of troubleshooting issues, what I can't deal with is being confused as to how that would cause me to have a misfire? It seems like I went from throwing about 3 or 4 codes a few weeks ago, doing a tune up, now I'm throwing 1. Just curious how this code would effect driveability.

thanks again.

I actually came up with that during my search. Looks like I've got a little troubleshooting to do. Thanks for your help!
