Does the 6-cyl manual run both of these? I've read it does but my car never does either of them. Any ideas why it doesn't if it's meant to? It also seems to leave the isc open as I get limited engine breaking on decel, (trip reads about 4 l/100 on close throttle, seen other cars do 1-2). Everything seems to be working fine...TPS set at 0.7v, ISC works fine on another car.

I unplugged the ics on my 5 speed because it gave me the s**t.
Theres a screw you can use to manually adjust the idle.

Not a big fan of no ISC, makes the gear changes jerky cause the revs drop too fast, not to mention the average cold performance

Pull your ISC, get some carby cleaner and clean out the screw section. They bind up with crud and jam open or start to operate slowly due to the binding on the thread.

Have you reset the ECU?
Pull the 'Eng' fuse for at least 10mins, instead of fully disconnecting the battery (easy to keep radio setting then) |

What's the screw section exactly? I've cleaned it out before but never noticed a difference really, probably worth doing it again though. Also reset ECU plenty of times, but it's always done it.

So clearly the ISC is open slightly. But really, if there was a decel fuelcut working it wouldn't matter since that will stop it making any power. Still does 4 l/100 instant fuel consumption at 100kmh, I can remember it reading 1 l/100 a long time ago, which is what I assume it should read when it cuts fuel. Also still don't get any lean cruise, just sits around 14.7. Not sure if the 2 problems are related.

That is a pretty low vacuum at idle. What is your vacuum at 750rpm?

Do you have the neutral switch wired to the ecu? If so check that it's working. If the ecu thinks it's in neutral fuel cut won't work.

That was 2000 vac.

Still interested to see what vac is at 750rpm.

idle MAP is 11inhg (ie 18 vacuum) so that's fine, gearbox neutral switch works (0v N, 5v in gear).
Pulled out chip and put the old bunch of resistors and crap back on, still no fuel cut but ISC seems to close as it reads 4inhg, same as without ISC. Maybe this is a difference between manual and auto from the factory?? dno about lean cruise without chip as I don't have the wideband sensor in the car. Also should note I actually don't get rev hang.

Ford quote 470mm of Hg at idle in neutral. This equals 18.5in of Hg. This converts to 9 psi of Vacuum. Are you sure you are measuring inches of mercury or psi.
If you are pulling 11in of Hg at idle, then that is only 5.5psi of vacuum. If this is the case then this will explain your fuel issue and lack of closed loop. If this is so then you have a vacuum leak and not necessarily on the intake, it could be through your exhaust valves. Is the cam and head stock? |
