MAP Sensor
Hi guys! I'm new to the forum so hello to all. I recently purchased a 1997 K Series MGF and it's a bit love hate due to an issue with loss of power on acceleration. I'm going through the checklist of likely culprits (already replaced and upgraded throttle body incl. sensor, replaced dizzy cap and rotary arm, fuel filter and HT leads, new plugs on order). I have a new MAP sensor on order and with it being a 1.9 MEMS with the sensor in the ECU I was wondering if anyone had any advice on how to access and replace the MAP sensor. I can see how to get the panel off (though haven't tried yet) but have seen some forum threads say it is soldered on. Does anyone have any experience with this and know how to replace it? Thanks in advance!

Re: MAP Sensor
I think everything in the ECU is potted.
How about tracing the advance/retard vacuum pipe from the head to the ECU and checking for leaks?

Re: MAP Sensor
Hey, sorry what do you mean by potted? As in irremovable? I've already checked the hose, it's tightly secured and in good condition. We ran a scanner and it came up with the MAP sensor as an error code hence looking to replace.

Re: MAP Sensor
Set in resin to prevent vibration damage. What scanner did you use? '97 engines were not OBD2 compliant and require T4 or pscan to give accurate codes - and even some of those can be misleading as the fault code systems were still being developed!

Re: MAP Sensor
Ah I see thanks. Used a snapon modi's edge but to be honest I don't really trust it. I need a specialist really but as I can't drive it anywhere I need one who will come to me!
