| Hard start with 2004 toyota tacoma. this problem began the day i drove it off the lot. sometimes the vehicle starts right up and other times it takes 3-5 attempts at starting. this nonconformity usually happens after its been driven and sits for 1-2 hours. the vehicle has been brought in for this intermittent starting problem 5 times. with 870 miles on the vehicle i brought it in and toyota said the spark plugs were fouled and changed them. the problem continued to occur 2-3 times per week. with 1500 miles we brought it in again and toyota said the problem was the electro magnetic current interfering with the injector circuit. they removed the ground wire cable out of the wire harness and said the engine started just fine. the problem continued to occur. the third time i brought it in with 9087 miles. they performed a tsb eg042-04 fpn-8122-04052, 0p eg4016. the problem continued to occur. the fourth time i brought it in with 9901 miles the technician could not duplicate the problem and said everything was in specifications. the problem continued to occur. the fifth time i brought it in it had 11.700 miles. toyota replaced the ube sub-assmbly e. the engine still has problems starting.*ak | |||

| My 2004 toyota tacoma has an intermittent problem with a loss of power, i.e. when i step on the accelerator, it fails to respond for a brief period of time. it is a problem when pulling out into traffic, as the loss of power has led to several near collisions. the vehicle has been to the dealer twice to diagnose the problem, without a clear cause, according to the dealer. research through an independent service shop points to a problem with the accelerator pedal position sensor. research on toyota tacoma forums online also seem to support this. the only viable fix seems to be to replace the entire throttle body, since the sensors are not available separately. this cost is over $1200, as opposed to a $70 sensor. the problem is intermittent, and can happen many times a day, or be absent for weeks at a time. three times it has resulted in a check engine light, with a tps fault recorded (the tps and apps are read as a unit by the ecu). the problem has not yet been adequately addressed. *tr | |||

| I purchased my tacoma in 2004 with 6000 miles on it. every since i bought it, it has been extremely high on gas, only getting between 240-260 miles on a tank. i have taken it to the toyota dealer and they could not find out what was wrong with it. it feels as if it has a skip in it. i now have 20,789 miles on it and when i took it to the dealer they recommended a fuel injection flush so i had that done but it still feels as though it still has a skip. this is only a 4 cylinder motor shouldn't i be getting better gas mileage? *nm | |||
