The Lean Burn system was an early spark advance control system (introduced in 1976 and continuing to the 1980s) that was troublesome due to the nature of the contemporary electronic components, as well ...
lean burn conversion - Allpar Forums
2013年8月13日 · The conversion is pretty simple, remove the wiring harness of the system, you can leave the sensors in the intake, they aren't doing any harm once disconnected. Distributor has to be changed, one with a vacuum advance is best, and sorry, the carburetor has to come off, it has some inputs to it from the lean burn and there is no ported vacuum ...

2014年5月5日 · Look at it this way: The Lean Burn system is an all or nothing system. If you keep it, keep all the parts working as designed. You'll likely get the best gas mileage that way. My 1981 Mirada is still running the Lean Burn, no issues there but it is a low mileage car.
‘81 New Yorker Lean Burn Delete - Allpar Forums
2019年8月6日 · The lean burn carb differed only in the addition of the throttle stop switch to tell the computer the throttle was closed, so leave it alone, no new carb required. Most of these cars, if fancy enough, had A/C and a rear window defroster, so should have come with the 100 amp Leece-Neville alternator and shouldn't "flicker".

If the truck isn't running well, find out why. Removing the Lean Burn components would be a big step backwards. Always diagnose first.
78 360 Lean burn/spark control questions - Allpar Forums
2024年2月22日 · To set base timing in a generation 1 or 2 Lean Burn system, the computer cannot have a vacuum signal, nor a signal from the carb switch. Isolating it was the quick n sleazy solution. This was actually an early type of throttle position sensor, used until 1980, when it was dropped in favor of the idle control solenoid.

I wanted to know if it would be possible to remove some of the smog components like the egr valve and the pcv valve without getting rid of the lean burn system.

2022年4月27日 · An even bigger issue than the Lean Burn carburetor is the stock carb does not have a provision for ported vacuum to run the vacuum advance. This ia an absolute necessity if you expect the converted car to run properly and efficiently. The Edelbrock has the ported spark advance. This is an older thread, you may not receive a response, and could ...
Lean burn? - Allpar Forums
2014年5月5日 · When tearing the lean burn and emissions systems off a car to make it 'run better', the car often ran worse and lost the good highway fuel economy it once had. The lack of 'oomph' may be partly due to a steep highway rear axle gear ratio, combined with a lock-up torque converter for lowered engine rpm at cruising speeds.
1984 D150 3.7 L6 Lean Burn no fire - Allpar Forums
2018年10月20日 · 1984 D150 3.7 L6 Lean Burn no fire. This week I purchased a "non-running" 1984 Dodge D150 with the 3.7 Slant 6 / 4-speed from a family friend, was told that it was running fine then stop firing. It has the module in the air cleaner, 12-wire and 10 wire connectors. Coil is not firing, single pickup w/o vacuum distributor looks fine, power to ...
