hi folks...
yet another "what is wrong based on symptoms XYZ..." thread...
so a while back when I was driving the car, pressing on, I suddenly experienced a jolt / jerking, I would say around between 3-5k RPM.
I have also had a few times recently, where I get home, and switch off to unload the car, when I try and start it up, it wont fire (turns over OK though), took a few attempts and some light pressing of the accelerator too.
I also had this unpleasant kind of grindy noise a little bit while attempting to start it, it did eventually fire.
so having read half the internet, my initial feeling on the jolt and jerkiness was coil packs, they are probably ancient. Sparks, I don't know when they were last changed but I am thinking quite a while...
the hot start problem, I have just checked and I had a new starter motor and alternator battery harness thingy fitted when the engine was rebuilt around 3 years ago (less than 10k miles), also new oil separator (probably nothing to do with this), among many other things, so I would hope it is not related to these?
other searches have suggested maybe spark plugs, or cam position sensor?
anyone care to throw any more suggestions? the car is actually going in to the indy in the morning, having all new coolant pipes fitted... and I have asked for the coil packs to be inspected / replaced, but I am not so sure now they are at fault....
