Hi there.
I am trying to identify the fuel system that is installed on my car.
I am going to replace the AMM on my car (it has failed to work). The previous owner replaced the original AMM (Air Mass Meter/Air Flow Meter) with one from a salvage yard, I think he put in the wrong one.
My car is a 1988 Volvo 240 wagon.
Are there any identifying marks on the car that would identify whether or not I had LH2.2 or LH2.4 fuel injection?
It seems that each (LH2.2 and 2.4) have their own specific AMM. The AMM I removed from the car has a serial number that ends in 016. 016 seems to belong to 2.4 injection, but that injection system seems to belong to 1989 and newer cars. My detective work tells me my car should have 2.2 fuel injection which uses the 007 AMM (serial number
007) as my car would be part of the 1985 to 1988 production.I understand that it is very important to install the correct serial number AMM on the car. That said, what would happen if I installed the wrong one? The is out of service now, and up til now the mileage and performance was not as great as it could have been. I have a feeling that I didn't have the part (correct) in the first place. Since I have to special order the new AMM anyway, I want to make sure I am getting what I need. (it's really going to be unfortunate if I order something, wait the two weeks to get it, and it's wrong).
Can someone help me identify my cars fuel system? Tell me what to expect if I install the wrong Air Mass Meter? Share any other interesting stuff I should know. I've been working on old Volvo's for some time now, but this car is my very first (ever) car with fuel injection (I'm a long way from my much missed 1979 with the good old b21a (just gave the car away last year, should've never done that!)).
Thanks, I really appreciate the help.
