When i try to fully accelerate from stop the car hesitate to speed up till it reach rev above 3k and the exhaust makes one time sound like if its clogged (""puff"") sound only at its starting to move. I changed the spark plug to Iriduim but still the same problem occurs.

i am having the same problem with my car 1999 Lexus GS 300 when i try to accelerate quickly from stop the car speed up slowly & sound coming from the exhaust like if its clogged then opened (**Bugg**) even that i changed the spark plug but without benefit.

Ok thank you i will try my best to find similar good product but cheaper one.

I have searched alot of place in the net to find denso parking sensor products that is used for Lexus but i couldnt find anything. I want to know if anyone know a website that is selling denso parking sensor products so that to buy from them directly.

I want to know what is the best way to gain more HP in very safety way without affecting anything in the car. What is the best exhaust system for lexus and toyota cars is it Borla or TRD or other brand? What about the spark plug which brand is the best one? What about the air intake system which brand is recommended? Is it K&N, APEXI, HKS or other brand? Is it useful to use Supercharge for normal use and is it require periodic maintenance like Turbocharge or not? My point that i want to get more HP in econmoic way without taking any risk to the car.

I heared that the only different for the engine is the injection type only so i want to know if its possible to change from port injection to direct injection. If its possible i want to know what i need to change.

I have toyota avalon 2005 which has 2GR-FE (3.5 liter) engine which is the same engine used in lexus IS 350 but because it uses direct injection not port injection like toyota avalon its engine is called 2GR-FSE. I know that the Lexus IS 350 engine (2GR-FSE) has more power than toyota Avalon 2005 model engine (2GR-FE) because Lexus IS 350 uses the Direct Injection, because of that i want to ask if there is anyway to modify the avalon engine (2GR-FE) to make it (2GR-FSE) so that to get more power. Is it possible to modify the Toyota Avalon engine (2GR-FE) to make it from Port Injection to Direct Injection so that to be the same as Lexus IS 350 engine (2GR-FSE). If its possible to make it plz inform me how to make it and is it useful to make it or not economically?

there was a buck sound coming from the left exhaust while i accelerate from zero but now after i changed the fuel filter this sound gone but the problem that the vibration which is coming while i accelerate from zero is still there so i dont know if this problem is from fuel pump or from other thing. Sometime the same vibration come in high speed so anyone have an idea about that or not.

My lexus 1999 gs 300 problems: - When i fully accelerate from zero vibration with sound coming from the end back of the left exhaust. The sound is like (Bang) and i dont know whats the problem,i have changed the spark plugs with one coil cause this coil was burning the plug also i have changed the one broken pipe connecting the air filter with the engine. Sometime when i accelerate slowley from speed 60 km to 80 km the sound of (Bang) is coming also from one side of exhuast which is left. Anyone who faced same problem or know how to solve it plz help me.
