Tick over help
Discussion
I have a 2011 Tvr S3 with a 2.9 Ford 2.9 with a eec1. Starts instantly tick over approx 950 rpm . But as soon as I touch the throttle it revs perfectly but returns to 2000 rpm. If i do the following
1. disconnect the idle speed valve tick over drops back to about 500 rpm
2. If i push one of the vanes in the air fow meters it drops back to the 950 only to jump up perfectly but on slowing stops at 2000.
Tried
1. Disconnecting throttle cable .
2/. Checking butterflies are shut.
3. adjustervstop right back.
4. Checked all over numerous times for air leaks.
5. 4 news tps fitted, new temp sensor, new idle speed valve , tried 2 other mass air meters.
I am really at the far end its next service may wdll be a cremation. Any help would be great or a efi expert in Lancashire Thank you Simon
