What sensors can make a car run rich?
A faulty MAF sensor is the most common cause of an engine that is running rich. The MAF sensor calculates the air, which is going into the engine, and then calculating the air-fuel mixture that should be added. If this is dirty or failed, it will cause the engine to run too rich or too lean.
Are there any problems with the Saturn’s series?
Saturn experimented with making these out of plastic, it was a huge failure. ALL of them failed, if you still own one of these cars and it hasn’t been replaced, it has failed. Symptoms include hard starting, rough idle, temperature gauge not working, awful fuel economy, poor performance, and stumbling, among many other things.
What kind of spark plugs do Saturn’s series use?
Most copper plugs fit this description. Narrow fine wire electrodes almost always cause problems, usually a p0300 and running like the car needs new plugs. The easiest thing to do here is just use the OE spark plugs, they’re inexpensive and just work. NGK BKR5ESA-11 (DOHC) and BKR4ESA-11 (SOHC). These have a higher than normal failure rate.
What causes a Saturn’s to slam into reverse?
This causes the car to “slam” into reverse and/or harsh upshifts, depending on which is worn. It will eventually destroy the line pressure solenoid, which will make for very hard upshifts. If left for a while, it will knock the input shaft nut loose, further worsening the condition of the shifts.
Why does my Saturn’s have a toaster head?
Some people run a 60-40 antifreeze-water mix as a preventative measure. The key symptom is massive oil contamination in the coolant, to the point where it has the consistency of a chocolate milkshake. The head is toast and the coolant system will need to be flushed thoroughly. This is only a problem with the SOHC engine.
