My 99 4.0 explorer has no power but idles fine. I have no1 idea what it could b

You may have a seized up caliper or collapsed brake hose or maybe a seized up hub or wheel bearing.

Thank u I was thinking something stopped up. But that is very helpful to me

Same problem but now check engine light is on and backfiring. Anything??? Ughhhh

You can get the code or codes the the check light is displaying most parts stores will tell you what the codes are for no charge. That would definitely help diagnose the problem instead of guessing.

Still think one of the calipers is seized up or brake hoses is collapsed because engine will back fire if you are trying to force the vehicle to go and it's not going.

Thanks for ur help. It was crossed wires. Running good now

You left out some very important information not mentioning you

Changed the wires or removed them.

Whoever's had th car b4 crossed some wires. I jus got it
