Car is a 72, Engine is a 71 Options

[martinef1963]

I wanted to know how would a 1.9L (BBK) 71 engine # W 0 074 343 would mix with a 72 FI system????

I've researched the FI parts and have found that the ECU that I have is Bosch 0 280 000 037 for 1972 engines, but the other associated parts, with the exception of the Throttle Switch cover both ranges (71-72 years).

I'm not at all well versed on the FI harness and it's compatibility either?

Her idling is "on roller coaster mode," sometimes she is just fine, and others she pisses me off.

I've read the Carb vs FI banter and really want to stick with the FI, but I need some real help on how this FI #$%^ works. I've read Paul Anders, Kjell Nelin articles and have done most of the parts testing.

Help anyone? (IMG:http://www.914world.com/bbs2/html/emoticons/blink.gif) (IMG:http://www.914world.com/bbs2/html/emoticons/headbang.gif) (IMG:http://www.914world.com/bbs2/html/emoticons/confused24.gif)

The car drove from California to Atlanta without any problems - the idle has always been an issie even when it had the original 1.7. The engine was swapped out with a 1.9L (BBK) - I have sent my mechanic an e-mail asking if the CAM is stock so I will have more info to offer once he gets back with me. It sat in Atlanta for another year and then was driven down to Miami.

The ECU and MPS are compatible - the one I have on the car is compatible with 71/72 ECUs - so I don't think that is the problem and I did the vacumn/ohm test and it held 25 PSI for over 5 minutes. On the ohm side of the house I got a 090 from terminal 7 & 15 were 90 ohms, and between 8 & 10 they were 360. Now the book calls for 350, but I don't think the difference is that significant - if I'm wrong please someone let me know.

I found the source of the gas smell in my engine compartment - looks like one of the injector on the passenger side has a leak - I haven't been able to isolate which one - I will probably switch both of them.

speaking of which - the injectors are still yellow - for the 1.7L.

Maybe I will get Mr.Bowlsby opinion on my situation.

I have purchased a 1971 ECU, FI harness, and engine harness and I will be installing them to see if there was a compatibility problem. I will keep you guys posted.

If that fails - I'm contemplating going CARBs - I'm almost at my wits end.
