So my vehicle is starting to become very temperamental so here’s the facts if anyone can help point me in the right direction:
†Starts first time every time when cold or when it’s left to cool down for approximately 30 minutes.
†Cold or warm it’s idle randomly jumps from 800 rpm's to anywhere up to 1,800 rpm's and will drop back down again at any time.
†After starting and driving for maybe 10 minutes, once the engine is warm, if you stop the engine and run into a shop for 5 minutes and come out again it will turn over and over without igniting.
†When it’s turning over like this, if you pump the throttle pedal it will slowing shudder and ignite after maybe 10-15 seconds of trying.
†Or alternatively if you put the key in and turn on the ignition and wait until the airbag light goes off (almost like glowing a diesel) it will ignite right away like normal (only twice has this not worked and we just had to wait until it cooled down).
†Even when driving the RPM's will rise so as it’s automatic, if you’re at traffic lights or a junction it can just jump in revs and the car will jerk forward so you have to keep your foot firmly on the brakes or if your coasting down a hill off the throttle completely it will still cruise at the higher RPM's so you have to use the brakes again to slow down, but again this just happens randomly without any warning.
Reading other articles there’s I’ve seen different symptoms similar but not the same, in those cases the main causes are a coolant temperature sensor, air intake sensor or just cracks in air intake pipes etc. Just hoping someone has had the same problems and could point me in the right direction before having to pay a lot of money going through all the possibilities, thanks!
