I need some serious help ! I was having problems with my airflow meter sensor so I replaced it. as soon a I replaced it; my supercharger started making noises . my car feels feels like it is skipping when it at a stand still. and I can feel air pressure coming from the top of the supercharger . Need help please

 

Is air actually leaking out somewhere?

 

Could be a lot of things from an air leak, fuel pump, bad coil(s) or supercharger problems.

You can eliminate the SC as a problem by disconnecting the SC drive belt and running it without it for a short period.

How many miles does the car have?

Have you pulled the diagnostic codes, if any? If so, post them and we can help you more. If not, get them read and let us know.

At idle, the system is under a vacuum not pressure, so you would hear air being sucked in.

Air leaks are definitely possible, but taking you have not touched any of these parts, and only the MAF, it may be related to that.

Have you replaced the MAF with an OEM or Aftermarket version?

If OEM (and you have the right part number), you may want to reset the ECU’s fuel trims (remove battery for a couple of minutes), or if you have an odb2 reader you can check the airflow and fuel trims.

If aftermarket, then get rid of it and buy an oem one. Then you could also try to put your original MAF in and see if the car runs ok.

This isn't the level of detail that's likely to get you any useful help.

What kind of noises?
I don't know what skipping means.
Where EXACTLY does the air come from?

 

it feel like air being suck in from the top of the super charger.I can put my hand on top of it nd fell the air from it. when I am driving it does not make that noise or skip. how do I and where do I check for air leaks ? and how is the sc drive belt ?

 

Can you point out where in this picture? The seals where it goes from the "V8" to the two "supercharged" intercoolers are known to get sucked in.

 

Hi, My name is Sandra, and I own a 2001 Jaguar XJR Supercharge and sometime when I am driving there is smoke coming from my exhaust. when I at a stop and I hit the gas; a cloud of smoke is behind me. it does not. happen all the time but often. and when I accelerate; it takes a few minutes before the car catches it speed. Need help.

 

Hi Sandra,
I'm a little confused. In November you were posting about a possible air leak in the supercharger. Did you resolve that problem, and this is a new issue?

Smoke on acceleration is often oil getting past the rings, in which case there should be evidence of it in the air inlet tube near the MAF sensor. Is the smoke a bluish color?

If you are not too far from Douglasville I would be willing to take a look at it.

 

Another possibility just came to me: The part load breather may be plugged, causing the crankcase to pressurize when idling at a light.
The part load breather tube is attached to the front left valve cover with a norma connector. Spread the ring from underneath with needle nose pliers to release and pull it off. Then clean the bore with a 3/32" drill.
