#3398 of 3453 '96 Regal jerks on light acceleration by adriver3 Apr 17, 2008 (8:12 pm)
Car has 165,000 miles. Has 3.8 liter original engine. Car has been very reliable. Recently did complete tuneup and replaced ignition module, which solved jerking at higher speeds, rapid acceleration Could current light acceleration problem be related to torque converter? if so, how to test it and fix it?

Replying to: adriver3 (Apr 17, 2008 8:12 pm) There is no thing as a tune up anymore. I realize it has different meanings to different folk. It used to mean replacing the points and plugs and rotor cap.   Did you replace ignition wires? Did you replace spark plugs with AC Delco plug?   At what speed and what gear are you feeling uneveness? Replies to this message: adriver3 (Apr 18, 2008 10:28 am)

Replying to: avonlady13 (Apr 16, 2008 3:05 am) I had the same symptoms on my 02. It turned out to be a plugged up catalytic converter, not a trans problem. The dealer replaced it under the smog warranty.

Replying to: imidazol97 (Apr 18, 2008 6:42 am) Ignition wires were replaced. Spark plugs replaced but don't know of brand of spark plugs but can check that--may be NGK. Typically 40-60 mph on light acceleration--even downhill with light acceleration...high gear Thanks.
#3402 of 3453 1996 Regal difficult to start when hot by kshiplett Apr 22, 2008 (3:59 am)
Hello. First time here. I have a 3.8 V6 with 112,000 miles. Stalled in traffic the other day. Pushed it off the street and allowed it to cool down for 5 minutes then it started right up. Two days ago it stalled again and I allowed it to cool and it started again. I drove it to work today and turned it off. Tried to restart and it wouldn't -- cranks fine but just won't ignite. Replaced air and fuel filters a few days ago. Thank you for helping. Replies to this message: imidazol97 (Apr 23, 2008 5:00 am)

Replying to: kshiplett (Apr 22, 2008 3:59 am) Is it giving a spark while cranking? Attach a used spark plug to a wire and place on grounded part of engine to see spark.   Is it firing the injectors? You can feel the pulse of use a 194 bulb with leads straightened plugged into the connector for one of the injectors while cranking.   Possibilities: bad battery connection, especially if you have a double layer positive (red) connector. Pull plastic back to see both connectors.   Crank position sensor. Camshaft position sensor. Some people have found splashing cold water on the crankshaft position sensor will change it and make the thing work and give spark and then start.   I have also read that a ground wire connection to the connector plate below the coils can stop the ignition system.

#3405 of 3453 1989 Buick Regal rough idle and stalls when hot by headach Jun 25, 2008 (5:22 pm)
My brother has a 1989 Buick Regal Gran Sport with the 3.1 Multi Port v6. It has 173000 miles on it and runs great on the highway. But ounce in warms up in city traffic the idle gets rough and tries to stall and sometimes show check engine light. If he put it in nuetral it stalls less often but still idles rough. I figured by taking it out of drive it will remove stress. He has replaced so many parts we couldn't begin to tell u. The ones he has replaced tring to fix this problem are the cat, plugs wires (ac delco)(bosch) (with the ac delcos the car wouldn't run and they kept cracking off in the engine)(bosch it runs and don't crack), several fuel injectors that were bad, fuel pump, fuel filter, map sensor and many o2 sensors over the last 72000 miles. He loves the car and it is his back up for when his olds alero is down. However he has put a large amount of cash in it since he bought it used in 03 when it had 100000 on it. Do you think it might be the fuel pressure regulator, mass air flow sensor or something else.
#3406 of 3453 2000 Buick a/c and heater problem by bdlabs Jun 26, 2008 (9:52 am)
a/c and heater work great when the car is cold. When the car reaches running temp, a/c and heater will not work at all. I have replaced the control module on the dash. ( it is the manual one, not the climate control unit.) I have tested all the relays in the circuit. I can manually turn on the clutch for the compressor and the high speed fans at the relay and fuse box. If I let the car cool, everything will work again. Thanks for your help. Paul
#3407 of 3453 Re: '96 Regal jerks on light acceleration [adriver3] by headach Jul 02, 2008 (7:21 pm)
Replying to: adriver3 (Apr 17, 2008 8:12 pm) I have a 1993 Pontiac Trans Sport with the 3.8 and it has been doing the same thing for about 2 years. I have replaced Mass Airflow sensor which helped but not it, Tune up and throttle Position sensor. I have yet to find problem. I heard it was the torque converter from several people but have had three transmission repair shops drive it and told me it is not the tranni or torque converter. Good luck i have given up and drive it anyways. It has 156000 on it so i am at the point i don't wanna put more money into it. If u hear it is something simply or it is the torque converter please post it i look hear often and would love to fix this. Thank you and i hope this helped
