Any warnings on CRC Mass Air Flow cleaner? 200 1988

Thank you for the response!

I blocked the preheat hose flap after the first replacement flap failed.
Over the years I have been through all the air, fuel and electrical systems more than once.

I had sever running problems some years ago and although the AMM Ohms checked out within spec it wasn't until I swapped it out with an AMM from a salvage yard that the major issue stopped.

I was wondering if the AMM cleaner would put that original malfunctioning AMM back into service for a back-up.

I was also wondering if cleaning the AMM would have a beneficial impact on my poor gas mileage. My mileage fluctuates from 15 to 20 mpg in city driving, running sole and unloaded.

In regard to the mileage, the only thing I have not done is replace the O2 sensor after the above mentioned sever running issue. So it could be fouled ... but that does not strike me a contributing to 'fluctuating' mileage.

Then again ... I did just replace a failed in-tank fuel pre-pump. Maybe it has been suffering all the time I have been trying to figure the fluctuating mpg. That pre-pump has not been installed long enough for me to check gas mileage.
