My ute drives fine when its cold once I have been driving for 45 mins or temp goes over half it will start running rough . when takeing off from lights it will nearly stall any ideas would be great not sure where to start

Whats the timing set at? Id be checking all ignition items for wear higher temps = higher resistance and more breakdown.

I'm not to sure about the timing what its set at and thank you I will start checking ignition items also how would I check to see what the timing is set at

Its gay as 304 dizzys with banana manifolds are pretty pooey . But put it into diagnostics mode and use a timing light on it. If you dont have a timing light google how to make one i think its one earth one wrapped around cyl1 plug top n the boot shoved over connected to a globe been a long time since that lesson.

What sort of running rough is it? Rough is USUALLY ignition or fuel. Do you have a pressure tester? If no wait til it gets rough running put a ziptie or clamps on fuel return line sometimes pumps get hot and start to fail.

I usually change coil & fuel pump with general service if I don't know history of the car..rules most things out.

Regularly do fault check on these,it's easy...if really game compression test.

If still got a miss start looking at ignition module & other things.

By the end of it not much left to check but you'll know what's working.

okay ill give that a go I have had some previous problems with the ignition module before put a cheap one in lasted few months and swapped back to the old one and ran fine until now

its running rough as I loss of power when accelerating nearly stalls taking off from the lights and idles rough at the lights

I have recently replaced the coil and the fuel pump

Alternators charging correctly isnt running on battery only at idle? Is it missing ? Does the dash dim? Sorry man need a little more in depth description.
