Replying to: the_big_al (Mar 31, 2009 7:40 am) We have 2 Impalas with the 3.8L. The 2001 now has 103k and the 2004 has 120k. In Sep-06 at 92k the 2001 suddenly started cranking longer to start. This car had always started on 1 crank. The problem started 1 week before my 6yr/100k extended warranty expired. Dealer replaced fuel pump and ignition module under the warranty but that didn't fix it and they couldn't duplicate the problem and of course no codes. Then it started stalling out intermittenly too, but it always restarted. My wife only does local low-speed driving and it seemed to stall out when it was cold, like the first drive of the early morning, after going a few miles. Both problems occurred randomly for 2 months and I spent many hours searching the net for a most likely cause. Finally it stalled after going 100 feet - her first start after work- and wouldn't restart. Towed to the dealer and left it there for several days for them to try to duplicate the problem. I had seen in my research that the CPS could be the problem but the service mngr (who was a very good) said the flow charts don't point to the CPS for the 2 problems when combined. I said to replace it as a last try because we didn't have a drivable car anyway. End of story is they replaced it at no charge, and the car's been fine for 2.5 years. I got lucky - it could have been an intermittent electrical problem. Repair history for the 2 cars: 2001 - upper intake coolant leak and cat converter (Chevy warranty), thermostat, fuel pressure regular, one rear ABS sensor, one front wheel bearing assembly, blower resister, fuel gauge sensor and the crank position sensor. 2004 - I drive this one 500 miles a week - one oxygen sensor, a thermostat, one front wheel bearing assembly, and a slow leaking lower trans coolant line. Overall, not bad for 223k total, and if the CPS had been diagnosed quickly, no major problem issues. They also get serviced - fluids, filters. The cars look good, still feel solid and always plenty of power.

time for the once a year oil change on the Imp... Since it rarely sees over 10K a year (it's a 2004-bought in October of '04 and only has 42K on it), I run Mobile1 and change it once a year. It was that time today. The only caveat?? Took me longer to change the air filter than it did to change to oil.... oh ya - I also flushed out the coolant too. |
