Default Help!!!!!!!!!!!!!!!!

So I am sitting in my car on the side of the road Typing this because my car died! It's current
90 degrees and I am about 50 mins in to my trip
It's not overheating. It has done this before but it's been since august I replaced a bunch off vacuume lines and though I was done but the weather started to cool down then too! The problem is that it will just start to cut out when you give it throttle. You can start it but you have to sit there and tap the pedal to keep it running. I replace the fuel pump and filter at the end of last July about 4k miles ago. I let it sit for about 20mins then starts up and runs like nothing happen! So maybe coil getting overheated/or going out. It seems like it only does this when the outside temp is over 90. I just drove to Houston "3 hours one way" and had no problems it was around 65degrees then! Any ideas and comments would be awesome!!!!

Where in TX are you? fuel pump may have went out again. mine started and ran great for 10 min then pooped out again and again. icm or coil may be an issue but seeing that you let it sit then it worked like nothing was wrong doesn't seem like a coil issue. coils either work or they don't.

Wiggle the temp sensor connection on front of water pump... Sounds like the symptoms I have when mine looses continuity

Scott, I've got a spare coil/icm and plate you can have if you want. Have you spaced yours off the head? ...if not, they could be overheating and acting retarded
