when is it time to replace the ignition coils what are the signs
i gets no power on the lower rpm at 1000 to 3000 then at 4000 it picks up like a beast somebody told me i am loosing electricity it might be the coils when i cahnge the coils around like putting the first on in the six one and the six one in the first one and so on (just the coil packs) it performs much better its almost like a different car then after driving for a while it becomes sluggish again
can anybody help me need feedbak thanks

I wouldnt recoment "switch them around" like you do mate, its unhealthy for your ride. The signs of bad coil booths/releys should be obvious, like missfire. When you change your coil pack I sugest you do it along with spark plugs (btw this is a good way to check which cylinder not firing, your spark plug will be clean with no signs of usage).

It wont sound so vague as it is if you would provide us with little more details, like what kinda car you drive and when was the last time you did tune-up.

Drive safely.

hmm, start with the basics, did you change the plugs, did you gap them correctly, did you install shitty Bosch platinum 4 plugs. tell us the full story and we can help you. also did you change the wires? know if they have been changed? little things like that make a lot of change

e36 325i doesnt have ignition wires, but yeah, it would be great if you give us something to work with

ha ha, you are right avlany. I am on crack, sorry used to being with the little engine that couldnt (M44)

yeah i do have Bosch platinum 4 plugs dont think they need gapping
thinking of changing them with the NGK BKR 6 EK or the iridium

I dont know why some folks bitc**g about BOSH, I like them. But in your case, no one puts 4 line plugs (BOSH Platinum +4) on Inline 6 engine. You have to change it to BOSH Platinum +2, and yes, they need to be gaped properly. You can do it in any AutoZone.

Drive safely.

If it's sluggish at low rpms, it could be the VANOS not working or not working correctly. Maybe someone here know how to test.

thanks
