Did the poor starting and stalling occur after the cleaning operation, or was the cleaning an attempt to address this issue?
If the issue occurred before, were the symptoms the same, or are they now different or similar?
Thanks pb. Cleaning was an attempt to cure the issue, symptoms are the same now.
Some background:
Car bought October 2018 92k miles, no faults.
Spring 2019: new spark plugs (Champion RA7YC), throttle body removed and cleaned with brake cleaner & toothbrush as part of routine service
Now at 106k miles, been running fine ever since (apart from occasional low-speed kangarooing) until...
Friday: warm start after a short run turned over 5sec or so before firing. Engine stalled twice and started running again on journey home. Check engine light came on when stalled and off again when running.
Saturday: disconnected battery, removed TB, MAP, plugs and leads.
Cleaned TB with rag sprayed with brake cleaner. Tried & failed to prise IACV from TB. MAP was clean, sprayed with brake cleaner.
Plugs were clean, gaps slightly wide on plugs 1&3, regapped to 0.9mm (35thou).
Reassembled, connected battery, fired straight away but idled fast @2000rpm and unevenly for 1min. Engine check light stayed on.
Turned off, unplugged & reconnected MAP, IACV and TPS. Started fine and idled smoothly @800rpm, engine check light still on and has been on since.
Sunday: turned over without firing from cold, 2 attempts for 10+secs. Unplugged and reconnected MAP, car fired and ran normally. Set off on journey, runs fine when not intermittent stalling, usually off-throttle or trailing throttle. Sometimes engine fires up again, sometimes coasts to a halt. Often turns without firing, hot or cold.
The poor little thing is clearly unwell but got us home last night I've found a source for an OBD connector, will try and get codes read on MES.
