[orbis-gte]

hi guys , i have a supra 7mgte with a low miles, it normaly starts good , and fast . but some times hazitate. the rpm jumps slowly to reach to 1,
and if u press gas, it the rpm goes up but u can feel as its miss firing , for few seconds and then it works good,
this happens rearly..

What have you checked so far.

 

[dumbo]

id check your codes, and does this happen when its hot, or just when its cold.

any smoke from the exhaust when this happens?

Cheap and easy thing to check might be the spark plugs. Install a new set for $15 and also maybe install some new wires. If anything it is good maintenance to do anyways.

Also if you dont know here is how to check codes

[i have changed the spark plugs recently. and it only happens when it worm,
the and code is good

check your wireing to your battery that the terminal posts are snug this was happening to me a couple days ago just undid the terminals and tightened them again and she was good as new or..... shooting out in to the park could be your starter?..... also check your cap a rotor basic maintance stuff that could screw you if they go untouched and unoticed

mine does the same thing too, only when warm, when cold it starts like a champ, think it could be starter?

I would say check your grounds, or your fuses. I had a car act that way some times, it was either it did it or not just came and go as it wanted. I had a fuse that was almost burnt out and it was the ecu fuse might check that.

i have tried that , but the starter is good . it starts well . but when it starts the rpm goes up like u are running out of fuel , after few sec it goes back to 8.0 and it runs normal . i tired it again and it workes fine , only when its hot sometimes not always, its like it trying to pick up to a normal rpm , but it just stuttering to be to normal rpm,
