the ......fuel pressure regulator is on the fuel rail near the rear of the intake manifold it is round in shap. i would first check to see if you have a problem with your O2 sensors. also i would have the TPS sensor checked. the TPS is what controls your idle. it is located on the throttle body is black in color and has a weatherproof plug to it. please rate this.........thanks

you may have two oxugen sensors on your yukon. if so the oxygen sensor that controls that bank may be bad. from what you mentioned in your complaint, it sounds like it is the oxygen sensor.

Check the vacuum line to the fuel pressure regulator and check to see if the fuel pressure regulator has gone bad. Give the throttle body a good cleaning and the injectors too. Do not use carb cleaner, it's to corrosive for the gaskets used in the throttle body. The other thing too that would cause this is a stuck or bad EGR valve, Try cleaning the EGR valve too since your cleaning the throttle body. Good luck and keep me posted.

Black smoke comes from exaust when I start. Could it overfuel and how can I fix it if its a new carb on my 88 2e 12valve


assuning there is nothing major wrong, get some forte injector and use it as recommended. I once had a renault laguna diesel fail an MOT test, a roadworthiness test that is, on emissions...it was absolutely chucking out black smoke but the engine ran well. I put 2 bottles of injector cleaner in the half full tank and went out for an eighty mile drive revving the engine in the lower gears. I returned to the testing station an hour and a half later and the engine was running perfectly.
Alternatively, assuming the engine runs well but is just a little smokey, have it terracleaned, this will remove most of the carbon deposits from the engine/exhaust and should increase the life of your engine simultaneously improving fuel economy

2001 chevy prizm jerks when in gear heavy smoke out of exghuast


It will help Matt if you would have said what color the smoke is thats coming out the tailpipe. White heavy smoke will be antifreeze getting in the combustion chamber.Could be head gasket,cracked or warped head.Black smoke would be fuel system pumping gas in making it run rich,And not able to burn the fuel completly.

Black smoke is caused by excess fuel that has entered the cylinder area and cannot be burned completely. Another term for excess fuel is "running rich." Poor fuel mileage is also a common complaint when black smoke comes out of the tailpipe. Black smoke out the tailpipe is the least cause for alarm. Excess fuel will usually effect engine performance, reduce fuel economy, and produce a fuel odor.

How did the fuel get into the cylinder in the first place? Some of the causes of excess fuel are a carburetor that is out of adjustment, a faulty fuel pump, a leaky fuel injector, or a faulty engine computer or computer sensor. If black smoke is present, check the engine oil as in the white smoke example to make sure excess fuel has not contaminated it. Do not start the engine if a heavy, raw fuel smell can be detected in the engine oil. Call your mechanic and advise him of what you have found.

Hope this helps; also keep in mind that your feedback is important and I`ll appreciate your time and consideration if you leave some testimonial comment about this answer.

Thank you for using FixYa, have a nice day.

My 2011 chevy colorado 5.3 engine seems to be running very rich jet black tailpipe, poor gas mileage


Do a pressure check from the fuel rail. It could be your pressure regulator starting to go bad. Is normal for Chevy and GM.

I am getting poor fuel economy. The truck has 88,800 miles. Fuel filter, and air filter were changed in 2011. The tailpipe is black and I run fuel injecter cleaner every 3000 miles.


Poor fuel economy can come from bad fuel or tune up.Try switching to a gas with a higher octane and give your truck a full tune up.This should help your fuel economy out a little.

I've changed the oxygen sensor and the O2 sensor and new plugs on my 97 dondge 3.9 van and it still blowen black smoke (rich) seems to run real good on top end but theres is a flat spot where theres no...


Black smoke indicates no air, check your air filter, if you have done that and it is ok, check the PCV valve. Thats about all that I can suggest. Hope that helps.
