Question about 1999 Oldsmobile Intrigue

2 Answers

Ignition Problems I have a 1999 Olds Intrigue with approx. 35,000 miles. It runs great. Everything works great. Except for some intermittent ignition problems: Only in the early morning I have a lot of trouble getting the car to turn over. I turn the key and it sounds like it's going to start, but doesn't ignite. I can take up to 20 times or more before it finally turns over. And it does always eventually turn over. I only have this problem early in the morning. I live in Southern California and it's summer so it's not that cold in the morning. The other problem is that as I'm driving the car and I come to a stop light and I press on the brakes and as the car is ideling it dies. It just dies. So I turn off the radio. I turn off the A/C I put it in park and then try to start it. Again, like the early morning problem it can take 6-12 attempts before it turns over. I took the car to 2 shops. The first shop found no problem. They tested for electrical problems. The second shop flushed the fuel injection system. They couldn't find anything else wrong. Since the fuel injection service the car has been better starting in the morning. But it still dies out at stop lights. I don't want to have to buy a new car. But if I keep the Olds I've got to have it fixed properly. I read what one person wrote about changing the ignition switch. Both shops felt that wasn't the problem. Help!

Some Possibilities:
Fouled/used up spark plugs causing weak ignition. Dirty air filter. Defective distribution, ignition cables. Improperly operating choke/automatic choke mechanism. Improperly set idle speed and/or idle fuel mixture. Mis-adjusted timing. Fuel system issues like clogged up ports etc... ECU computer problem(causing timing, mixture problems). Overtightened belts.

Which of those above things did the mechanics actually check and rule out? This shouldn't be too difficult to troubleshoot. As long as the engine has strong sparks with proper timing, and compression is good, and the fuel/air mixture is correct, and that mixture actually gets into the engine without problems then the car should run fine. So, ask the mechanic if he/she verified all of those things.

I think in most cases you may have a weak fuel pump or a clogged fuel filter. Even though your fuel system is run by pressure it doesn't always prevent the car from stalling if the engine is starved because of a bad filter or faulty fuel pump

2002 Olds Intrigue ignition switch does not work properly. Sometimes I have to "jiggle" it for several minutes before it will work. Yesterday I had to move the shift lever before it would work and t

there is no connection between the ignition switch and the shift lever. One turns the power on to run and start and the shift lever prevents start until neutral or park is set . Therefore it is possible that the fault is not in the switch but in the adjustment of the neutral switch on the transmission.

I have a 2002 Olds Intrigue that has an intermittent problem with the air conditioner/heater not working. No indicator lights show during this time and occasionly the Cruise light comes on. No real pattern...

Follow the blower wires. I believe you should find a relay. I suggest testing it as well. Make sure it is good. Also make sure fuse is good and secure. Test your control switches and check all the vacuum lines and wiring

99 olds intrigue ignition switch problem

You have to replace the ignition system, all the 99's came with an anti theft unit built in. The ignition is built into the system, so that could be the reason why.
