97 dodge caravan Engine Fuse blows

I have a 97 dodge caravan engine 3.0. When I start to accelerate my engine fuse 20amp blows. I does not occur everytime but yesterday, it did it 6 times and is now getting looked at. I am just curious on what causes this. I did recently have my spark plugs changed so I am thinking something may be arching.

I do have codes that previously came up for my fuel injectors (P0203, p0206). Another code I have is p1294 idle speed performance.

What 20 amp fuse, where is the fuse located?

It is under the hood on the drivers side. It says Engine 20A.

It has been awhile since I had got my van looked at but the problem was finally solved for me.

I was having an intermitten problem with my 20a fuse blowing after barely pressing on the gas pedal. It would not happen all the time just whenever, so one day when I went through 6 fuses just to travel to my parents house, a couple of guys from work looked at it. Thankfully the fuse blew when they looked at it, so I no longer felt like I was crazy,

They found a wire setting across my throttle body that had worn threw the casing and there were arch marks on the metal, so they wrapped it up with electrical tape and zip tied the cables up. So far my van runs great.

Hope this helps anyone out there!

Late or not, thanks for coming back and posting the fix.
