You can doubt all you want. I've seen it first hand. More often than not an engine that runs rough at low RPM has some sort of intake/vaccuum leak.

ok man, cool down, ok that was the problem, the gaskets. anyway I am happy the sputtering is over...

Happy 1000 dave!

1,000! WOOOHOO! I'm taking the rest of the day off

A leaky intake gasket will allow extra air into the intake. This in turn will cause a leaning of the air/fuel mixture (since the air is coming in from a point that is beyond the Mass Air Flow sensor, the ECU doesn't "see" it and therefore doesn't compensate for it). This lean mixture causes roughness at low RPM. However, as the RPM's increase, the air/fuel mixture is enrichened to the point where the small intake leak is not enough to lean it out. So the engine runs smooth. That's my guess, anyway.

Gee Dave thats a bloody good diagnoises for a 'Spare Parts Assistant'. you should move into the workshop.

I agree with you entirely.

so i think that dave won that one!!!!!!!

so dave you think it it a gasket ??
i have check all the vachum line 3x.

im going to changed the fuel filter just because the thing does have 100,000 miles now and it is going to go bad anyway here soon.
how much do a set of head gaskets cost???
or what could i do to fine out if it is a gasket leak???

Let's see....... quantity vs quality? I watch for Dave's.

apologies for previous caustic comment.

spudering? Is that when my SVX spews mashed potatoes from the intake??

Thanks for the positive feedback guys....I appreciate the nice comments


I wasn't trying to "win" anything though....just having a friendly disagreement. If I came across as trying to be Mr. Know-it-all I apologize. Sometimes my sarcastic behavior gets the better of me.

Thanks for the laugh Glenn. Working on a Saturday stinks, but starting it off with a good laugh really helps



Dave



P.S sent you a PM

mine would spudder some times when i was going and at light it would do the same thing and sometimes stall but still no light. we hooked up a select monitor for the 92 svx and it said cam sensor so i changed the one next to the battery and it still did it the i changed one of them under the alternator and i havent had any problems since

so at the end it was a cam sensor... neither a weak valve nor the gaskets... and as Dave said it was a friendly disagreement.. I wonder I didn't have any symptoms since the thing I did with the engine, but maybe in the future I will experience the same phenomena... and Rocket, let me tell you something, I do not consider myself as a mechanical expert, I know a great deal of everyday's mechanical symptoms, but I do not consider myself as a mechanical engineer. maybe an SVX certified plastic surgeon... still though, I am proud of my knowledge...

Spear,

I am proud of my knowledge...

That much is clear.

I guessed gaskets because he said his check engine light was not on. Assuming his check engine light was working, the lack of a light would rule out an electrical problem. So his case is truly strange....a bad sensor but no check engine light.

Weird!
