Yes, you have symptoms of ignition break down. primarily plug wires. Double check plug gap & wire gauge (7mm 8mm). Ok, Bosch air meter has two adjustments, using a very long allen wrench (thinking 5mm) insert throu removed plug forward of air boot top of housing. with engine running turn 1/4 counter clockwise, may try several adjust until performance has improved. This IS NOT a fix only a personal diaagnosis temp. this should improve engine performance. The proper fix is lenthy. If improvement is noted then let us know and we will help the permanet fix. Rick

The car jerks from time to time & makes a small backfiring sound. It also looses power from time to time


I would think it's either coils or ht leads or spark plugs breaking down

"have spark at coil down to dizzy but no spark at plugs"
this can mean only 2 things.
1: spark wires are dead. all 4, kinda hard to believe huh?
2: the dizzy is way off time. so time the dizzy and now spark
lands on each wire term.
if not a dizzy engine, post exact version of engine and country.

Up hills & under a load --could be the EGR Valve
as you have a high vacuum load

The temp goes up on hills & yes the coil packs
could break down. That won't show up in the service
bay the way a dealer tests it.

Not the Throttle Body or Injectors
Sounds good & makes them money
first.
That is what they do,after 3 visits & parting
with your money, then they will work on the misfire
Sad isn't it

Never go to a dealer. Try a local shop

could try another coil pack they do break down with time but the year of the vehicle would help ,check the mass air flow sensor in the air intake pipe as i think this is more than likely your problem

Make sure the HT leads are secure. They might be popping off, causing it to not fire on one cylinder. I always change the plugs and leads at the same time to keep them the same age. HT leads break down rapidly and need regular replacement.

sounds like coil pack, when your coils break down due to age the spark then jumps from the side of the coil to the alloy head, i would recomend taking the coils out and getting them tested to be 100%.
