running engine in all going sweet then all off a sudden starts missing like a popped engine removed lower plugs spun over sounded as it should? tryed new coil set new leads removed primary and secondarys check there sealed all ok running out of ideas only thing the vmop is flashing up on sensor check on the commander can this put the engine into limp home?? also tryed new map sensor??
have you made sure that the hose going to the pressure sensor on the firewall is still on?
Yeah checked that, any other ideas??
fitted a oil metering pump that is now within spec,, tryed a ignition amplifier still the same????? runs but all over the place with no power try to rev it and sounds like its missing?? going to do wiring checks but running out of ideas???
defo got the injectors set up correctly on the PFC ?
how many miles left ?
yes the maps been checked over was running fine just coasting along and started to miss?? confusion?
blocked fuel filter ?
what was the injector duty and was there any knock ?
brand new filter knock was 4 not sure on injector duty? on my understanding the crank angle sensors control the timing of the front and rear rotors \'right\'???
so u changed the Apexi to use 1680 injectors?
and the lag settings
yes its all been set and checked by greg the guy that does the mapping at rx motors??
Coil pack wiring,have you changed that/checked it.
I had very similar symtoms recently on another car,it turned out to be coil pack wiring loom.
we hav a spark at every lead im wondering if i hav a break in the loom from the crank angle sensor to the ecu so the timings not 100%
forgot to say tryed another apexi ecu mapped with same engine spec still not cured carryed out wiring checks on all fuel and igntion loom nothing abnormal running out of ideas ? going down the alarm myth now tracing alarm wiring and removing the immobilizer side of it !!! HELP
Throttle position sensor? Probably not, but worth a check to make sure it\'s in spec.
cheers nikp yes its ok going to fit new \'secondhand \' loom build it all up again and see ! cut out the immobilizer from the alarm 2nite one less thing!
right in the last week the engines come back out and stripped the block to be 100% there was nothing thats gone back in the engine \'nope\' had to buy another set of water seals due to one splitiing booo 60 miles they got alot of use!!:eek: the mystery goes on? rebuilt the engine ready to drop back in fitted a new loom incase theres any breaks.. if it still miss-fires going to hav to do some serious loom checking!!!!!:flamed
engines back in with a new loom STILL THE SAME tim at rx motors has a delivery mid morning !!!:2Mad
That\'s a bit of a b*gger! :(
i dont often giv into defeat but hey i hav !!! just hope tim sorts it and it dosent cost £££££££££££££££££££££££££££££££££££££££££££££££:Grrr and that its not something stupid! im going along the lines of a broken wire some where??
Have you tried swapping ECU\'s? (Just to eliminate these things)
yes we put lums in theres nothing we havent swapped or tested baffled ??
:-(
sorry to hear about all this dude. You have shown your commitment to be second to noone, so don\'t give up it will all sort out for you ..
cant belive it tims got to the bottom of it already he is a god !!!
one dodgey spark plug -sparking but not very healthly apparently!! brand new plugs 60 miles and there knackered that was costly! 10s and 11s too!!!
The one thing you didn\'t check!! And probably the one that should have been checked first! But none of us thought of it......although Dave should have known better! ;)
