#16 of 20 engine lights on or off by hjhildo Mar 06, 2009 (10:14 am)
The lights go on sometimes and off whenever. Took to dealer and was told misfire in cylinder. Need a repair for $3600.00 to a 27000 mi 2006 TB. Of course, they found it right after the warranty goes off. Was told they are having problems with them. This is obviously a TB problem and not mine. I service the vehicle constantly. Had electrical problems, module, air leaking because poor manufacturing, etc. Do I have to replace the head like they think I do or what do you do for a misfire in the 6th cylinder?
#17 of 20 check engine light 2003 tb by tcantillo Aug 17, 2009 (7:16 am)
my 2003 tb with 4.2 six 90k has a check engine light said it was a temp sensor had it replaced and code reset. after 200 miles or abouts it comes back on with same code. just came back from a 1500 mile trip.it ran great even with check light got 23mpg at 75mph with air. just replaced water pump as it had a wobble not leaking. now i'm told it might be theremostat, yet it is working find.feel like they are just changing parts?

Replying to: prestonschevy (Sep 25, 2009 10:41 pm) I would get a 2nd opinion before forking over that kind of money to fix it
#20 of 20 Rpm issue and SUV wont accel correctly by heezyjos Oct 26, 2009 (4:52 pm)
my suv when i drive it i willl hit the gas pedal the rpm's will go up but the car seems as if its idoling like im revving the engine in drive is the best way to describe it and i cant get the car to go over 40mph it seems. autozone checked my check engine lite and they advised that there was a problem with the coolant sensor however would this causethis type of problem. i also just had the battery replaced and the battery is only a few weeks old we checked the connection on the battery an they were not tight but autozone tightened them for me and it is still doing the same thing. any ideas on what the problem could be?
