Engine Starvation / Fluttering - ZR-1 Net Registry Forums

JThomas · 08-13-2009

Within the last month, I have driven my '92 Z and have experienced a situation where the car sputtered/fluttered under acceleration. It almost seems as if the car had bad gas or something. After continued driving, the problem seem to go away.

At the time of the incident, the car had a half a tank of gas (Premium)

After the first occurence, I added an injector cleaner and last night when it happened, I added a fuel additive.

Do you think:
1. Bad gas
2. Injectors going bad
3. Clogged or dirty fuel line
4. Dirty or clogged fuel filter
5. Fuel pump issue
6. Wrong time of day??????

The car continued to drive each time, but it was a noticeable loss of power / acceleration.

Any insight would be helpful.

Thanks.

So does it drive ok at steady cruise but breaks up under acceleration?

Somewhat okay at steady cruise, you can sense the difficiency, but more noticeable under acceleration.

After filling the tank today and driving from Lansing to Detroit and back, no problem whatsoever. (150 mile round trip)

How old is the fuel filter?

I was having a similar issue when my fuel pump(s) were dying. Might not be your issue, but worth checking pressure.
