3500-4K Stutter Step...........


jgmgti

Recommended Posts

On acceleration at approx.3500-4K my tii(1972) will miss and the car will

stutter for 500 rpm or so.Past 4K all is strong to 6500.

Any ideas?

That is an unusual condition. Have you checked your fuel pump flow (gpm) and pressure (psi) at the KF pump inlet? What about the pressure maintenance valve for partial clogging? How old is your distributor, coil & plug wires?

Maybe a rpm-limiting rotor (that is partially "stuck")???

Fresh Fuel pump,re-built K-Fisher,wires,rotor all new and good.

I'm thinking shit gas,maybe crack in rotor?

Thanks for any and all advise is appreciated.

Are you using Premium gas (from a high turnover station)? Maybe just a tank of bad gas.

Carbon tracing inside the distributor cap may also cause some freaky arcing.

Other long shots:

Spring under dist. cap missing

Bad rotor

Plate inside distributor slightly loose

Points bounce/flutter

Valve adjustment slightly off

Spark plug gap slightly off

Also, some cheapo ignition wires are known to be bad right out of the box. The screw-on ends won't have a tight fit to the wire.

I installed a Pertronix kit in my tii (old distributor), then pulled it out after I bought a new distributor. I may someday put it in my VW (009).

Maybe one of the thin (cheap) wires on the Pertronix unit is broken, causing the problem. Make sure the wires didn't get exposed when pulling them thru the distributor housing hole.

Are you still running the ballast resistor on the coil? What kind of coil do you have? Does your car have a starter relay next to the coil? Maybe this is bad.

jgm: I would have called but am busy wrenching on my tii before I forget what goes where. My wife keeps asking when the car is going to run again. Are you home this afternoon?

Now, back to your problem. Since you are using a "red" coil with the Pertronix, do you still have the stock ballast resistor installed? If so, does it get real hot shortly after you start the engine?

Otis: You get good attaboy points for your quirky responses. Ja,Ja,Ja,Ja.

    BMW Neue Klasse - a birth of a Sports Sedan

    Unveiling of the Neue Klasse Unveiled in 1961, BMW 1500 sedan was a revolutionary concept at the outset of the '60s. No tail fins or chrome fountains. Instead, what you got was understated and elegant, in a modern sense, exciting to drive as nearly any sports car, and yet still comfortable for four.   The elegant little sedan was an instant sensation. In the 1500, BMW not only found the long-term solution to its dire business straits but, more importantly, created an entirely new

    History of the BMW 2002 and the 02 Series

    In 1966, BMW was practically unknown in the US unless you were a touring motorcycle enthusiast or had seen an Isetta given away on a quiz show.  BMW’s sales in the US that year were just 1253 cars.  Then BMW 1600-2 came to America’s shores, tripling US sales to 4564 the following year, boosted by favorable articles in the Buff Books. Car and Driver called it “the best $2500 sedan anywhere.”  Road & Track’s road test was equally enthusiastic.  Then, BMW took a cue from American manufacturers,

    The BMW 2002 Production Run

    BMW 02 series are like the original Volkswagen Beetles in one way (besides both being German classic cars)—throughout their long production, they all essentially look alike—at least to the uninitiated:  small, boxy, rear-wheel drive, two-door sedan.  Aficionados know better.   Not only were there three other body styles—none, unfortunately, exported to the US—but there were some significant visual and mechanical changes over their eleven-year production run.   I’ve extracted t
