...while driving.? I have a 1999 Oldsmobile Intrigue with about 95,000 miles. It has the 3.5 Liter engine.

1. When I start the car, it sometimes will immediately cough and die on the first attempt. It usually starts on the second attempt. It has done this in a range of outside temperatures, both with the engine hot and engine cold.

2. While driving the car, it will occaisionally hesitate on acceleration - usually during the first couple minutes after starting the car.

3. While cruising at certain speeds under low to moderate engine load, the engine will surge; depressing the throttle to accelerate causes the surging to go away.

All three of these problems have gotten progressively worse over the past few weeks. Any ideas?
 
Yea, get a new car. May I suggest a Honda or Toyota.

3 things instantly come to mind:

Fuel pressure regulator
Ignition Switch
Crankshaft position sensor, which will usually set an SES light.

I can get much more specific if youd like, but you seem to enjoy searching:)

In what world does a transmission cause a hard starting issue?
 
I had the same problem with a 99 Intrigue, 3.5 with 92,000. It was the ignition switch module. $150 If I remember right. No problems since it was repaired.
 
The same world where spending an enormous amount of money on a rice car to solve your problem!

Perhaps BHR should not visit this forum then.
 
For me the same symptoms were a bad FPR

Similar symptoms, there was a torn diaghpragm in the fuel pressure regulator, so fuel would leak into the vacuum control line on higher vacuum, but not on higher throttle (lower vacuum).
To test for this type of failure, let the engine idle, then remove the vacuum control line from the fuel pressure regulator and see if a few drops of gas leak out. If any gas drops come out, you have found the problem.

I believe the crank position sensor will set a code....so its less likely to be the problem.
