Try disconnecting your rev counter, see if this makes a difference, honestly, my mate had this type of problem i will find out what the remedy is and get back to you

you have the older 1600i with distributor ignition yes?? Then its easy.
The rev limiter on these cars is on the rotor arm in the dizzy. Its a spring on a weight that as it spins to a certain speed allows the contacts to stop connecting and then stop firing (lots of flames if you do this right!!!
)
Anyway, just go out and get yourself a rotor arm without the limiter on it. Finished!!

WTF??? No RS1600i EVER came with a dizzy. Sorry MadMac you have been misinformed in a massive way.
As for disconnecting the Rev Counter not sure how this will affect the rev-limiter?
Good Luck anyway.

Hello mate
Just kidding about disconnecting the Rev counter, just stalling for time, while i found 'enlightenment' ( ie help ). The rev counter is just an output of the ecu, and in no way effects operation, so ignore this!
First off lets get to the problem. When you get to 5500RPM, does the engine 'cut' like its reached the limiter, or does it start to misfire? If it starts to misfire, read the post further down. If not, read on!
All the data for engine speed comes from the pickup sensor in the bottom of the gearbox bell housing. This could be dirty or faulty and giving false info to the ECU, so check this first. First check this is sitting properly in its 'hole' in the housing, and check that the cover plate is properly securing it. Also when checking this, take out the sensor and carefully clean the face of it wiht a tissue or soft cloth ( NOT sandpaper or a wire brush ), then smear a little copper grease (not too much) across the face before refitting.
Next follow the lead from the sensor round the back of the engine til you get to a little round 'multiplug' this connects the sensor to the main ignition wiring loom. Check this is not loose and all the connections are okay. If anything appears amiss here, try getting holds of another gearbox sensor that works, fit it and see if there is a difference. If not, go insde the car, undo the cover plate, pull out the ECU ( CAREFULLY ) and pull off the multiplug connected to it. There should be numbers on the face reading one to twelve next to respective pins. look for pins 5,6 and 8, which are the pins for the wires from the sensor, and check their not damaged. Finally, carefully with a screwdriver, prise the back cover off the multiplug, and look at the back of the pins to check the wiring connections arent loose ( DO NOT remove the pins from the back and get em mixed up!! ). Try this little lot 1st, if this dosent work, according to the 'Ford supplementry manual for the RS1600i' the problem lies wih your ECU; which is bad news im afraid.
Any questions reply here or email me

This is from the ford workshop manual on Mk3 escorts with K-Jet injection on it. The rotor arm with the limiter has been circled.

. There was no RS1600i with a distributer from the factory. Am 100% certain on this. Ford released a separate workshop manual for the RS1600i as it was significantly different from all other CVH engines. The spark is provided by the twin coils mounted on the right ( as you look at the engine bay ) this is controlled by the ECU and this gets it's signal from the special flywheel which has a magnetic tooth and is read by the sensor mounted by it. The system was desinged and manufactured by Atlas FarzeugTechnik GmbH. If you have been told otherwise you are misinformed.

Hmm.... You sure there was an ECU on the Mk3??? 
I thought the first Escort to run an ECU was the S2 turbo, and even then it still used a lot from the MFI system and then they change it to the KE-Jettronic type system.....
Oh I dunno!!! I'm just very confused now!! I didn't ECU's came on the cars pre 1986

Er, S1's and 16i's had ECU's altho I believe a turbo still has a dizzy as well.
A dizzy and an ECU aren't mutually exclusive, the dizzy just provides the signal for the spark in the same way the flywheel sensor does on the 16i.
I take it from this you've never owned a 16i

MattRS1600i is correct, hes even got the name right (do you know what that is in english? ive always wondered). The MK3 escort RS1600i was possibly the first production car (defo THE first ford anyway) to run a computer controlled ignition system. Otherwise everything at that time used to run dizzy and coil set up which your talking about.
The ECU you on your car controls the Fuel injection system, in which the injectors are electronically operated, whereas the old MFi system was mecanically operated/controlled.
If you get fast ford magazine check out the RS1600i buying guide a couple of issues back.

Ahhh. Never mind, another person educated in the specialness of a 16i isnt a bad thing......for future ref they also have unique front suspension and an alloy cylinder head with larger valve throats, higher lift cam and solid valve lifters, quite a different beast from a 3i and well worth owning.

Yup, its amazing how people still dont realise two special RS were made on the mk3, the RS Turbo and the RS1600i, hence my sig for the 'classic' description of one ( to the un/misinformed that is )
