Disconnect the car's battery for 5 minutes, then reconnect it. This should reset the check light. If the problem still persists you might've installed a sensor incorrectly or corroded one with the degreaser.

My eclipse won't start after I degreased it and rinsed with water

This is why some supernatural (intelligent design force) created WD40.

Water Displacement.

If you are old enough... you would remember the dead cars lining the road-way after a decent RAIN Storm.

High voltage systems... particularly like your DISTRIBUTOR hate moisture.

If you are in a hurry... spray down your SPARK-PLUG wires with WD40... use compressed air to blow off all standing water (especially around your SPARK-PLUGs) ... Pop off your distributor cap and sop up EVERY DROP of water from the inside with a clean tissue or paper towel.

If not... open the hood .... disconnect the battery ground terminal, open the distributor (read a few chapters)... and let everything air dry.

Next time you degrease any engine... put plastic wrap all around the DISTRIBUTOR before you start.

Drive safe & Happy motoring!

Code137 check engine light on

Voltage low on the O2 sensor. Bank one sensor one. Could be the sensor, But I would unplug it and check the plug ends for corrosion first. White and greenish color. Clean them and plug it back in first. Clear the code and drive it. If it comes right back on(after ten minutes of driving), replace the sensor.

Decreased engine, now it shudders & idles rough

The water has gotten past the plug boot seal. Pull the plug tire off the plugs and use some compressed air to blow out and dry the plugs. Some times the water can really get deep so don't pull out the spark plugs.

Repeated PO171 Lean Code:2008 Pontiac Vibe

First thing i would do is take the mass air flow sensor off and clean the small thin wires inside with a non-chlronated brake cleaner let dry for 10 minutes then re-install.If that does'nt help then check the fuel pressure it could be a weak pump or clogged fuel filter.Then check for vacuum leaks and next i would have the injectors cleaned.

2004 Dodge Stratus R/T 2.7 V6 90k Stalling on idle and when coming to a stop.

There is several possibilities that could be causing this: Here are a few good probabilities:
1. Dirty or fouled Spark Plugs. Pull them one at a time, inspect and clean and regap them. Replace if necessary.
2. Worn Wires. A great way to see if your wires are bad: In total darkness: Start your Engine and look under the hood. Do you see light blue mini sparks dancing all around? If so new wires!
3. Idle Air Control Valve malfunctioning.
Unplug and check and clean the electrical connections.
Remove the Idle Air Control Valve and clean it as much as you can, and let it dry.
Reinstall, replug connector and check operations.
I took the liberty to look up the parts on Autozone...No I don't work for them!
Available at Autozone: Part #AC333 for around $110.
4. Throttle Position Sensor malfunctioning.
Again: Unplug and check and clean the electrical connections.
Remove the Throttle Position Sensor and clean as much as you can and let it dry.
Reinstall, replug and check operation.
Available at Autozone Part #TPS336 for around $77.
Let me know if this helped, or if you have additional information, problems, or questions. Feel free to contact me at!

Oil leak

The oil pressure switch could be leaking. It is common on the 2.8 V6's. Clean the area off w/ engine degreaser, dry it off, then let run for a few minutes to verify the location of the leak.

1999 Town Car began running very rough - suddenly.

When cleaning your engine, water/degreaser went down the spark plug ports. Try using a air compressor blow gun to remove the moisture from around the spark plugs and boots. The water was causing the engine to misfire on 3 cylinders at first and as the ports started to evaporate the moisture, the less misfiring was occuring. Dry thouroughly and hopefully coils do not have damage to them. Also check to make sure the boot is making good contact with the spark plug.
