Question about 1988 Pontiac Fiero

1 Answer

I have a 1988 pontiac fiero GT with a 2.8 v6 and automatic transmission. I recently experienced a problem when I left the highway where everything seemed normal. As i appoached the first stop at an intersection I braked normally. As I slowed to a stop the car stalled out like it would if you had a manual transmission and didn't push in the clutch. I put the car in neutral and started the engine again. It idled at about 1500 rpm. and stalled again when i put it in drive. After several attempts I managed to get it home again. Any ideas. Thanks Brian W

    Yeah my sister's 1988 GT was exactly the same. Looked on the web and found another owner who fixed that problem. It was the torque converter lock up solenoid. It mounts under the valve body side cover on the driver's side. I got the parts and gaskets from DACCO Transmission. Installed along with new filter and Dextron VI high fluid. SWEET!

Small puff of smoke on startup - intermittent


I have seen this on old cars, my suspicion is that the seals on the valves are a bit worn. This allows some oil to get through during start up. Since it quits smoking, I would not be overly concerned. However, since it burns a quart every 1-2K miles, I am curious what the compression is. My Fiero does the same thing (occasional puff of smoke on start up) but does not need oil between 3,000 mile chages. It is a 2.5 liter. Here is nice tip: check compression on all cylinders, then recheck it adding a teaspoon of 2 cycle oil to the cylinders (one cylinder at a time). Some have said to use conventional oil for this, due to higher viscosity, but I always thought it might foul the spark plugs. If the compression goes up, it is ring wear, if not it is leaking through the valves.
