Q: I recently installed fog lights Ranger XLT 4x4. I used factory, where is relay on 2004 Ford Ranger

I have been driving my 2000 Ranger 4.0 for about an hour, engine starts having smoke from the hood. Checked oil, down .5 qt, put some in. Not overheating and temp gauge not rising. Checked under hood after a few minutes of stopping and could only smell a bad smell. Nothing showing on fire or burning or overheating. What are these rangers know for when it comes to engine heating up? Thanks for your time. What seems to make the problem better or worse? Not sure

I pulled up to a friends house it ran great, i go to leave and its running so rough i cant even get down the street. Its backfiring thru the intake and the exhaust it coughs and sputters, absolutely no acceleration and then it dies. Its undriveable. I replaced the wires and plugs cleaned the MAF sensor and im about to put a new filter on. Seems to idle ok sometimes, until i put the manual trans into gear then it wants to die...sometimes i can keep it going by pumping the gas, litely pushing the gas or just keeping the gas pressed down to the floor. Othertimes it wont even idle just starts coughs sputters backfires and dies. I been having to take the bus to work and i really need to figure this out and get it resolved as its my only vehicle. Any help? Many thx.

The radiator is leaking? As long as I keep putting water in It, I can drive it. But I'm afraid I may make the situation worse since I don't know exactly know what the problem is.
