should i put some seafoam in my oil before a oil change to clean it up?? should i do seafoam to the brake booster??

[LiCelsior]

get rid of the 87 and put some 93 in there. put some chevron fuel treatment also.

u dont have to put the seafoam in the oil but u can. pcv valve if ur running the seafoam.

I had that same hesitation at the same speed when I first got my '93 LS, tried Seafoam in the motor and gas tank but still hesitated...figured it was a misfire so I replaced the plugs and wires and it fixed the problem...hope this helps

Yes she'll run like a burrito is in the tailpipe if you use 87, use 91 and shell be happy.

Make sure the timing belt was done around 190k mileage, if they haven't been done the spark plugs, and water pump should be replaced while your in their too. Like Joe said the fuel treatment for your injectors does good too, I'd save sea foam for last if I were you. Errr run synthetic oil like mobil-1, and pay attention to any noise the car may be making. These cars have a habit of warning you when something is due to be changed way ahead of time if you turn down the music every once In awhile.

WTF take it back and demand your cash back.

The plugs are all the same from what I know on 1UZ's. Talking about giving the engine a refresh though, I'd also say to change all the seals, gaskets and hoses as well.

[92 LS400 RIDAH]

O TRUST ME WEN I GO BACK AND GET MY CAR IF IT AINT HOW IT USE TO BE OR BETTER THERE CATCHING HELL, YALL DONT KNOW HOW HOT I AM:saiyancrunks:

[mdenoga]

I bet they probably forgot to connect a hose that was removed when doing the job. Always speak to the service manager if you are not getting any results from the advisor.

[92 LS400 RIDAH]

i really hope so

[92 LS400 RIDAH]

MAN I STILL AINT GOT MY CAR BACK , THEY CALLED ME TODAY AND SAID THEY STILL TRYIN TO SOLVE THE PROBLEM?! WTF?? I GO TO GET A TUNE UP AND I STILL AINT GOT MY CAR BACK IT BEEN SINCE MONDAY:rules:

[92 LS400 RIDAH]

update- dealer called me and said they put wrong spark plugs in and theres 2 spark plugwires messed up? my thing is i told them i wanted new spark plug wires in but they said my old 1s are ok? now they telling me they got to get $800 for new plugs wires cap and rotor now? why do i got to pay for sumthing they did wrong?? i think the wrong plugs trigured alote of stuff on my motor to go bad what yall think? i talked to the manager she was like aw you got to consider its a older caar with alote of miles so things will go wrong? wtf! the car was running like a lexus wen i brought it up there so dont be talking that :saiyancrunks::saiyancrunks::saiyancrunks:

[92 LS400 RIDAH]

i might just go get the car towed to my hose, cuz if they did do it there aint going to be no warrenty on the parts, carquest or naa got the parts for lifetime warrenty i think, so what do i all need to do a tune, CAP AND ROTOR IS THERE 2 ROTORS?? PLUG WIRES? THE CAP TO HOLD THE WIRES DOWN AND SPECIAL CLAMPS?? WHAT I SHOULD GET???

[OneSODA]

Did you take the car in for a full tune-up with plugs,wires,cap and rotor, or drop it off for just spark plugs. If you dropped it off for a full tune-up with everything it doesn't matter if they messed up a plug wires. It was going to be replaced anyway. Ether way your car should come out running the same or better. I wouldn't put Carquest and Napa parts on my Lexus. OEM is the only way to go IMO.

[92 LS400 RIDAH]

JUST PLUGS, I GUESS THAT THREW IT OFF, NOW I GOT TO GET CAPS, ROTORS, WIRES , CLAMPS M STUFF NOW I GOT TO PAY $655 NOW:pat:
