| I left GM and Dodge trucks. So I went to Toyota thinking that they had higher standards and quality, but was i wrong. I bought a 2007 5.7 liter Tundra that has developed a piston slap like a diesel, this is not what I bought. I was told by Toyota that this was the GREATEST engine Toyota has ever made... well THEY DO NOT BACK UP WHAT THEY STAND FOR.. I have been to the dealer a half a dozen times about this, and called Toyota Corp.and had 2 Reps down from Chicago 3 times just to tell me this is the nature of the 5.7 top of the line high performance engine, and i just have to LIVE WITH IT. Thats BULL... they are not going to stand behind their product. ( BOTTOM LINE ). Now I have to listen to this all day long and what will happen when the miles rack up? or i go to sell it and resale is reflecting this issue? You pay over $37,000. you would think that it would run and sound the way it is suppose to be, especially for a Toyota? I'll NEVER BUY TOYOTA AGAIN, if they don't make this right. and i will TELL EVERYBODY, I PROMISE. DO NOT BUY TOYOTA TRUCKS... BUY AMERICAN. | |
toyota tundra V6,003. engine cranks, but doesn't start right away.drove on highway,when I slowed down to get off highway the truck stalled, tried to re start, but would only start and keep running with my foot on the accelerator. continued to drive ,but when I came to a stop the engine would die.would only re start and drive with my foot on the accelerator. the next day it stated up ok,but engine idled a little rough. Is my fuel pump bad?

Replying to: Mojaveman (Jan 24, 2009 8:04 pm) 1st--I spoke to a 20 year mechanic about engine oil type for my 08 5.7. I was told that these new high tech engines(especially Toyota) have very small and narrow passages in some parts of the motor, which make it difficult for oil to pass thru especially during cold start ups. That would explain the ping while cold. My 08 revs high during start up, but I do not hear a ping. I use a FULL synthetic oil.. 2nd--As far as piston slap during low rpm acceleration, that sounds like a fuel octane problem. I dont care what anyone says(or any manual says), use 91 octane in your tundra. You must be running BAD fuel in your tundra. Use fuel from Chevron or Shell. 3rd--My last suggestion. Do to your tundra what I did to mine. ( Let me clarify that at no time have I ever experienced piston slap during start up or during low rpm acceleration). For several months, I researched a cold air intake system and a plug in computer chip for my tundra. Understand that these tundra's are equipped with stock air filter systems that ARE A JOKE. The engine can't even breath. No wonder it only gets 13mpg in the city and only has 381hp stock. I removed the stock air filter system and self installed an AFE cold air intake box in 1 hr. I already felt a noticeable difference in throttle response. And you know what MORE COLD AIR entering in the engine means--better gas mileage, more hp, and more torque. Then I put the icing on the cake by self installing a plug in UNICHIP computer chip to the tundra's ECU. Understand gentlemen, these 5.7 motors can generate tremendous horsepower and torque, but are tuned DOWN to meet safety standards. The tundra stock computer chip is programmed to allow the engine to generate only a small portion of its capable horsepower, torque, and gas mileage. (THEY GOTTA KEEP THE OIL COMPANYS HAPPY BY MAKING SURE YOU FILL UP YOUR TUNDRA'S FUEL TANK AS MUCH AS POSSIBLE). The UNICHIP I installed safely tells your stock tundra ECU to produce way more hp, torque, along with increased gas mileage. These 2 totally safe modifications to your tundra will cost you about 1100.00, will not void any factory warranty, are do it yourself projects, and will allow your tundra engine to effeciently breath and burn fuel. What does it all come down to?? At least 37-40 more HP, at least 35-40 more TORQUE, and a 2-3 MPG INCREASE. AND VERY POSSIBLY NO MORE ENGINE PING due to stock air intake system... |

Replying to: luke21 (Feb 18, 2009 11:47 pm) Today the battery was dead again and wouldn't take a charge. It was VERY old, so we replaced it. This did not solve the idling problem... My fuel filter is only 4 months old, I don't think that is the problem. Would an O2 sensor cause this? Already scheduled for some maintenence on Wed. I'll let you know what they tell me about this Luke. Any other ideas or explanations would be appreciated before then. thanks.
