    I drove my 1990 f250 quite a distance, i would say about an hour drive to my home and it started to shake then as i pulled over the motor shuts down, then i let it cool down for about 10 min then it cranks up no problem, but shuts down when i shift the gear into drive

The TCC solonoid is bad I have changed hundred of these there is a square coector of the front side of the transmission, this is the connector for the TCC ( torque converter Clutch) it has a tab lock put your finger nale under the tab or a smal screwdriver and lift gently and pull the connector off the car will now drive when you put it in gear but NOT have 4th gear and theck engine light may come on you should get this fixed as soon as possible you have to take off the side transmission cover the TCC is in there only buy one directly from the GM dealer no one else trust me on this, and also change te transmissin filter and gasket while your there.
if this information is good plese give me a fixya!

Bubbles transmission fluid


I'm not sure the bubbles are telling you anything. When the transmission or power steering is working, you can have bubbles in the fluid.
One possible cause for the stalling at stops is a faulty torque converter lockup solenoid.

1990 Buick stalls when coming to a stop


Sounds like the torque converter clutch solenoid is bad. Unplug it and see if the problem stops. Unplug the 4 wire plug on the front of the transmission.

Car died and wont start


The fuel injector motor or called the Idle Air control module is not the failure. The fuel pump is overheating and dies out. Thus when letting sit a while the engine is starting up again.
I woult take vehicle to local shop and have them replace the fuel pump , I suggest not getting taken for a complete tune up. Just the fuel pump is the most cost effective way .

Starts fine, Idles fine, Drives Fine for a while


you might want to chk. the crank sensor and or cam sensor. sounds more to me that it could be fuel problem. chk. fuel pressure. pump could be on its way out. don't be fooled by hearing the pump running as they sound like they are pumping but there not, at least not enought pressure to keep it running. pressure should be around 50 p.s.i.

Sounds like the lock up torque convertor in the transmission is stuck in the engaged position.There is a sensor switch under the hood that can be temporarily unpluged but leaving it unplugged can ruin the transmission. Take it to a tranny shop.

Stalls out


lisalavin,

You said,

My 1990 Buick century stalls out when in park after idling for a minute or two and stalls out when brake is applied. last night it did this every time I had to stop or make a slow turn it also started shaking a bit but if i released gas a little bit it would stop. i thought the shaking might be the cvu joint as it needs to be replaced but it started doing it on straight aways and hills also but would still stop shaking if gas was eased up on. Closer to home when it was stalling the only way I could get it to stay running while I put it in drive was to have one foot on the brake and the other on the gas. Is this a matter of changing the fuel filter or is it something more complicated?

It can be one of many things causing this!
1. Low idle, needs to be raised
2. A vacuum leak, needs to be diagnosed.
3 The choke, if it's when it's cold or the engine is cold and not up to running temp.

4.But, I'll l bet it's a idle sensor

Or last and probably NOT a broken baffle in the cat converter!
this usually happens more often not just with the stop but even when driving!

Bless you,
huuum
You really need a good honest HANDS on diagnoses!
