i have a situation that needs some explaing. i own a 93 4 cylinder camry le w/ 166,000 miles on it. during da 5 yrs that i have had it i have nevered had any problem w/ it until now. on saturday it was running fine on da freeway, but a block after i got off da freeway the engine seem to sputter. it countinued for about 3 blocks until the car finally shut off. i pulled 2 da sided to examine the problem & i started to play with the spark plug wires, since they recently gave my problems. after a few minutes da car started but when i put it in drive it would shut down again. this would happened 3 more times. when it did finally start i drove 3 blocks to my friends house. da next morirng it took several tries to start my car but it failed. on my 5th try it worked, but when the car was idle it would sputter. now heres da funny part, when i reved da engine da light sputter would go away. after allowing my car to warm up for about 20 minutes i headed home. it ran fine except when i was at a stop light. i then put da car in nuetral to get rid of da sputter & jumped on da freeway. during my 20 minute drive i had no problems, my car ran perfectly fine even at 75mph. when i got on da main street da rattle cointinued when i was at a light. yesterday i took it to my nechanic to get checked out. i had him do my routine oil change since i needed it & i had him replace da spark plug wires. my car not starting was due to my faulty spark wires, but it did not solve why my car would sputter while idle. my mechanic had told me that why water pump was leaking & my radiator was clogged. ever since i bought this car i nevered had the timing belt or da water pump changed & out of the 166,000 miles on da car 54,000 is all my doing. so, can this sputtering be contributed to my leaking water pump, my need to change my timing belt, da radiator, or is there some other factor that can be contributed to my situation. my mechanica also quoted me at $375-450. i called a toyota reapir center and the quoted me at $400-500, is this a correct pricing? my friends brother said he would do it for $275, but i have nevered had him do any work on my car. i have already opted for my mechanic to do the job since his people are more familiar w/ my car. so please feel free to give any feedback. thanx for your time. slikk
