Bellow and DSM10000 - your guys are awesome with massive knowledge,

I agree and will leave it as is.

Happy seeing you progress.

Almost certainly you will and saving your energy, time and dime for those is more important. We'll be here to help in any way we can. Good looking car you have there - forgot to mention that before.

Dear Team

I have now nearly got my car up and running, apart from on major issue

1. the idle is ok just under 1k revs

But, when you put into "D" or "reverse", you have to massively build up the revs, it goes past 3k to move the car, even then there is no power

I suspect the maf, i have removed the maf and cleaned with contact cleaner, but no difference, it seems the original one, tomorrow, I will remove it again and then remove the actual sensor insert with torq plus tools, and try to find a replacement for this,

all vacuum lines are in place when you at the engine, not sure about the below.

Any advise form anyone? before i have the merc star diagnostics put on?

thank you team

I will confirm this later , but I recall a friend buying a 202 some years back with exactly this symptom and it was the MAF ( Mass Air Flow ) sensor on the air intake that was the issue , as the engine management system was not detecting the correct airflow .

I will speak to my pal later on , but from my memory I'm fairly sure that was the trouble , and a new MAF cured it .

I have now had a look at the atf dip stick, and photo shown, there seems no obvious oil, it there something at the bottom of the lipstick. I have checked with carnstand still, and also with engine on, no significant difference. Some photo attached.
1st photo shows car at Stan still, 2nd photo shows whilst engine was running, and 3rd photo shows water coming out of exhaust.

Should I add/ top up the atf oil tomorrow??

ATF level needs to be checked with engine running and car up to full temp , otherwise you won't get correct reading ; without being able to drive the car you won't get it up to full temp easily , you would need to let it idle for a fair while and even then you won't get ATF to full temp , but you should see a difference . Before checking dipstick , run the gear selector back and forwards through the full range of positions a couple of times , if it still reads low , I would suggest adding a SMALL amount of ATF at at time and checking in between .

Too much ATF can be as harmful as too little .
