My injector light came on my 156 V6 a few weeks ago and kept coming on and off intermittently. Whilst the light is on, the throttle response becomes very sluggish.
I took out the glovebox, unplugged the white connector blocks, sprayed them with electrical contact cleaner and refitted them, but to no avail.
Then it was suggested that I try unplugging and cleaning the throttle relay by the battery in the engine bay.
This seemed to solve it, but then the light reappeared a while later, before then disappearing for a few weeks. The car was running perfectly again!
All was well until my commute this morning when I hit a massive pothole and the car bottomed out. Injector light came back on immediately and car is now driving like a dog again.
Before I try taking the glove box out and checking those connections again, does anyone have any other ideas as to how I can get to the bottom of this? The intermittent nature of the fault seems to suggest a loose connection somewhere rather than the actual throttle potentiometer needing replacing, though I defer to anyone else with more experience than I.
Any ideas fellas?
As an aside I think this also suggests it is time to change the dampers as the original ones are still in place and the car is now fifteen years old and really struggling with broken road surfaces and speed bumps. Time for some Konis I reckon...
