In the AC request circuit there is also a low pressure switch. If the switch behaves erratically (due to faulty switch (connections) or just enough pressure in the system) the AC will be switched ON - OFF - On etc (there is some debounce in the software of the ECU). This can explain the erratic behaviour of the Idle speed, as the ECU wants to set the idle speed for when the AC is ON / OFF

The amount of fluid which has to travel trough the pipe is only dictated by the bore of the master cylinder and the (pedal) stroke. and is independent of the volume of the pipe. A smaller pipe is a little more restrictive flow wise. Why not just make up a mockup (won't brake the bank) and see if it works?

Hi Tom, @tomcattom You could have used the already present oil temp sensor on the left side of the oil gallery cover just under the turbo oil feed line, with the benefit of it sitting in the oil flow.

If all the testing etc goes right I'm in for my SE @mike_sekinger

😪😡 I have to work that day. Maybe I can find somebody who wants to swap / exchange that day. Keeping my fingers crossed.

Try some new wires from the podmotor to the pod module

A red hot resistorwire is not good ( except in heaters). I would check the current through the resistor, and measure the voltage across the resistor and the at the coil. If they are right then the wattage of the resistor is too low. If not then somethings else is not right

MAP Sensor has a range of 0 - 2 bar. Baro sensor has a range of 0 - 1 bar with a piece of foam over the inlet port. From the outside they look the same (except for the foam piece)

Just curious, (maybe @mike_sekinger knows) but are these dimensionwise the same as for a 1990 SE. (I know there are some extra holes for the ABS sensors and the webbing is a bit "wider" to accomodate the hole for the handbrake cable. More numbers means price reduction? Where is the sweet spot?

Hi Sparky, If you take of the hubs, can you let me know the thickness off the seal? The dimensions are 48 - 62 - ( 7 or 8 ) mm (should be printed on the seal) I know what I took out of mine but I'm not sure it is the right thickness.

The new pot/switch will have 5 connections, 3 for the pot and 2 for the switch. remove the old pot part from the PCB and fit the new one onto the pcb with the 3 connections. The 2 wires you have to connect to the 2 connections on the switch part.

The one LOTUSMAN33 mentioned is a potentiometer with a switch. Part of the missing part of the potentiometer is still attached onto the PCB marked VR. Just try a 10 KOhm potentiometer with a switch (lineair) should be easily available.

I guess you are referring to the broken potentiometer, is it the metal part with the 4 small lips attached to the black part as shown on your photos? If so it is a potentionmeter with a switch, the value is usually printed / engraved on the metal part.

The ECU's for the various esprit models are the same, it is the MEMCAL (which contains the calibration for the specific engine) inside the ECU which is different. If you buy a new (remanufactured) ECU then you have to take out the MEMCAL from the old and put it into the new ECU. Spray pattern OK? filters inside the injectors OK? What is the fuel pressure at the fuel regulator? Above is not correct. Yes there are 6 injectors, 4 primary ones and 2 secondary ones and they are not the same. The primary injectors are peak and hold (low impedance, around 2 ohm). One for each cylinder. They are driven in pairs (1 &4) and (2 & 3). Each pair is driven by a single MOSFET in the ECU. When they are commanded to open a "high" current is used (for quick opening), however the current is measured and after opening of the injectors the current is regulated down to a much lower value by the ECU in order to keep them open for the desired length of time (right amount of fuel). The secondary injectors are high impedance injectors (around 14 ohms). They are also driven as a pair. They are driven by 2 (out of 4) outputs of one of the QUAD drivers. These injectors only come into play in the high power regions. For injection of the right amount of fuel the ECU relies on information from the outside. As the car is starting (idling) it looks like the ECU is doing its job, but relies on information from the outside. If that is wrong then........................................... You seem to have an error 33 (MAP voltage) so fix / investigate this one. (check cabling etc). Also make sure that the fuel system (pressure, filter etc is well into spec). Reconnect the solenoid of the CCP back, see if the error 26 goes away. (BTW the descriptions in Freescan of error 26 are wrong). This can also happen if the lambda sensor is not OK. (among other things)

Which ALDL connector are you using? (behind glove box or the one in the rear relay box).
