Car was at operating temperature and just stalled and wouldn’t start without giving it a bit of accelerator. Started back up but would not idle at all. Any ideas what this could be? Just tried it again today after letting it cool down overnight, same story. Started and idled at around 640rpm, got to operating temperature, stayed there for around 10 minutes then just stalled out and wouldn’t start again without throttle. Fingers crossed someone’s come across this previously and knows how to fix. Cheers!! Link to comment Share on other sites More sharing options...

A tune problem with the idle can be sorted out in the driveway. You log idle air error and adjust the idle airflow increments accordingly to match the requested rpm. This is done in park and drive with aircon on and off. No dyno is needed for idle tuning. Further info is available on the PCMTec forum. Back to the thread commentary, if the issue wasn't present before the listed mods, it isn't tune related. Perhaps the rest of the mods should be listed to give a more complete picture Also never rule out stupid bullsh*t and assume anything lol Edited 28/02/23 09:30 AM by Puffwagon Stupid autocorrect Link to comment Share on other sites More sharing options...

The tuner recons it could be the oils thinning out at operating temp. I’m running the oil that they have recommended (Penrite 10w50 full synthetic). He also recons that none of the mods I’ve done should be affecting the idle at all. Here’s a list of the mods I’ve done to it: Flex plate bolt retainer Pulsar 3584 gen 3 turbo Yella terra billet flexplate Boundary oil pump gears Boundary oil pump backing plate ARP head studs Crow cams race valve springs Bosch 1250cc injectors (injectors aren’t installed currently) Walbro 460 fuel pump (pump not installed currently) Turbo side intake Throttle body elbow upgrade Stage 2 intercooler kit 4” turbo back exhaust Genuine ford timing chain tensioner Atomic timing chain kit External wastegate with screamer I asked about the 4” exhaust possibly being an issue due to back pressure but was told it wouldn’t be that.

Puffwagon Trust me bro...

Just gotta wait until a scanner or laptop is connected to see exactly what happens at the time it stalls. Link to comment Share on other sites More sharing options...
Marto48 New Member 8 Member For: 2y 2m 21d Posted 28/02/23 11:24 AM Author Share Posted 28/02/23 11:24 AM Yeah I thought that’d be the case, just got a bit worried when he said it sounds like low oil pressure. Cheers for your input and fingers crossed they can figure it out for me! Link to comment Share on other sites More sharing options...

Let's have hope and wait for the results Link to comment Share on other sites More sharing options...
