ok guys and ladies: have 195,000 miles on 4 door suzuki suv(see title) and love it. no tire problems, buy the yokahamas every 35-40,000 miles. work as courier, 20 mpg, replaced left rear wheel bearing at 170,000 miles. problem: at 180,000 miles check engine light came on, cruise control was disabled, engine ran rough fluctuating between 550-850 rpm, engine died at stop lite, suv was very hard to start before starting finally. took suv to dealer, they said $1,000 to clean passages of carbon, replace egr valve. 6 hrs to do job, took 2 1/2 hrs, asked for discount, SORRY. anyway, fine for 2 weeks, then same symtoms but after dealer said no codes, i drove off and later the check engine lite disappeared and i had cruise control and engine was ok. now, this happens every 2-3 weeks and goes away, then recurres. a friend at vw shop said it could be the "throttle body" unit against the firewall in the center of the engine compartment, but big bucks at the dealer to replace if problem. i know, i know nobody else has this many miles on the "new" 2006 (which was a great suv and deal, i paid $22,000 for it) but if you have had this problem on the xl-7 v6(same engine) please post final resolution, i'll do same.
