Ignition problems after 10 minutes

Hi,

I have a problem which I have not being able to nail down, hope you can help me.

I have a Windstar 96 3.8 L.

Few days ago I start noticing a failure on the engine behavior like one of the spark was not working properly, So I though it was either the spark or the cable, so i change them but problem persist. So that lead me to believe it was the fuel injector so decide to take it the next day to a workshop, BUT the night before while driving it felt like not only one spark was not doing ignition it felt like 2 or three were not doing it right, my vehicule could not move any more and I could here explosions on the exhaust system.

The mechanic picked up my car and took it to his workshop. According to him he had to change 3 sparks and also the cables. I was actually there when they change the last one. When they start the engine it was running very stable, so I took it for a little ride 3 block and called to be GOOD. So I took it home 10 block away from home.

But later that day I was taking my family to a party and suddenly start felling the same problem again, first it felt like 1 spark, I told my wife and decide to turn back home; while returning to our home it felt like it was running out of working sparks and barely make it to workshop.

At this point I don't know what it could be wrong looks like something is heating up and causing the engine to fail... my mechanic told me it could be the "Coil" and/or the Gasoline Pump. The mechanic plug in a manometer to gasoline pump and told me the read out 35 something.

I will highly appreciate your comments.

Re: Ignition problems after 10 minutes

Did he change the front 3? If there were bad plugs and wires, they probably all need changing. It also could be a coil problem but why did he just do 3 plugs and wires?

Re: Ignition problems after 10 minutes

He changed two at the back and 1 on the front,

He was trying to narrow the problem by guessing I guess. I'm definitively not happy with his performance and would change from mechanic.

At this point looks like my problem is electronically related as also some friends have indicated me that.

I also want to mention I have notice plug cables are really hot and according with some friends they should not be like that. They indicate the Coil could be overpassing voltage leading to a heat up on cables.

Re: Ignition problems after 10 minutes

A lot of current runs through the wires. I wouldn't be concerned about the heat. Find a shop that knows what they're doing. You can also get any codes read for free at an Autozone. The light doesn't have to be on for codes to be present.
