The most common cause of LH-Jetronic ECU failure is the hybrid control circuit. Our hybrid circuit replacement provides substantially improved characteristics such as lower power consumption and most importantly incorporates fail-safe functions that makes it practically impossible for the complete failure of the replacement circuit, and thus reduces ths failure mode of the ECU. We warrant our rebuilt LH modules for three years.

Common symptoms of a failing LH injection module

- (Porsche only) Fuel injection valves click when the ignition turned is on and engine is not running

- Engine will not run at idle

- Air-fuel mixture is too rich (this can damage catalytic converters)

- No fuel pump operation, but the fuel pump operates when its relay is jumpered

- The engine will not rev higher than 3000 RPM

- A/T cars: no idle speed regulation when switching between drive gears and neutral or park

- Engine will not start, spark plugs are dry and the ignition system produces spark.

This note from Gino

Hi Rich,

Just a quick note to tell you I got the LH in today and the car started right up! I could not believe it. I thought for sure my luck would not be so good!

I am thrilled with the fact that I probably saved myself between $1500-$2000 on this repair by doing it myself. I never would have thought I could do this myself.

Thanks for all your help and the many e-mails to diagnose and detail every step of the way. Please feel free to give my name/e-mail out to anyone that is looking for a reference. Thanks a million!

Stay well,

G
