Electric problems on my NM... I think it's the coil pack

[20vQC]

Hi guys. SOme days ago I was on the highway and I fel a drop in power that lasted about a second but a few times did that joke. Yesterday night I got the engine overheated, not too much but almost arrived to 120 degrees cuz a stupid water line from the heater got out of it's place . This morning I replaced all the water, eleiminated (again) the heater, and started the engine... after 15min of being running the engine shuted off... the AutoCHECK was OK. 10min later the engine restarted and when I was accelerating (in neutral but on WOT) I couldn't reach even 3000rpm! then shut off again by it self... 15min restarted and nothing was wrong . What could it be? Coil pack??? TDC sensor??? ECU??? please!

That is weird, i'd start by checking the distributer gear, then check the TDC marks on the crank/cams/distributor and make sure they all line up.

If it isnt ignition timing check fueling, i know if the fuel pump stops the engine will start and idle for a while but as soon as you open the throttle it will cut out.

When it did start was it idling smoothly?

I'll have to check out all these thing Yeah, idling was smooth, then when I did accelerate came the problem... Now I came from work and the ride was...well, was normal, nothing wrong! My fuel was ok... I had pressure in the rail!

COuld be.. but I don't know how to test it!!! One week ago I took out the air filter box a made a nice air intake... I hope that is not a problem...or THE problem!
