Timing is right buh i still lack power
 

i checked my timing today and its exactly at 10degree and my idle isd 900rpm and i know its suppose to be at 650rpm i tried checking the CPS and throttle and i cant get it to 650rpm. Ive had about 5 other supra owners around long beach that said i should feel the power at 3000rpm and i used to feel it but now i cant feel it at all it feels the same and when turbo kicks in. I can still barelly feel it. anyone have any clue wha can be wrong i got a code 51 buh it went away after i fixed it..

thank you for any help at all i want my car back to killing hondas on the street

maybe you have a leak or your turbo is gettin worn out, ct26's cant handle 12+ very long.

by the way i also live in long beach you've probably seen me driving around in an 89 white t-top with flat black rims, sadly my car is an NA automatic

88T did you fully warm up the car and bridge the T and E terminals at the diagnostic connector and then started the motor and checked the timing? Make sure you are setting base ignition timing without the ECU's electronic advance.

Run a compression test. I would if my engine started lacking power for no good reason except flooring it everywhere.

My cars idle is iffy. I can get it to idle at 650 only after driving it for a while with multiple trips. Any other time it idles around 800, probably because it isn't up to full operating temp. Thats why you must fully warm up the car before setting the base ignition timing.

y not just adjust ur idle adjusting screw?? to get ur idle down to 650

After the car has fully warmed up you can take the little arm off of the throttle body that has an adjustable rod end and see what the idle is with it off. If it goes down then you just need to adjust the rod end.
The other method is the dashpot screw. You can loosen the jamnut and turn it out till you get the desired RPM.
If method one and two don't bring it down then you will have to bring the throttle stop screw down a little but after doing that you will have to check your TPS to see if the idle switch in the TPS is still adjusted properly with a meter and feeler guage.

to answer some question i tried adjusting the screws i took it to a guys house who worked on a 7m and has a 1jz supra seen his car at work so i trust him. and he put it to its lowest it can go and i still cant get down to 650rpm. and yes the car was competely warmed up and still at at 900rpm ima have to wait till monday to do the compression test ill ask my uncle to do it. and i checked the timing when the engine was warmed up i just cant get it to drop


oowee623 ive seen your car around long beach...have you seen a 88 turbo in all white with momo racing seats and a 3inch exhaust its a targa top
have u seen a gold and block top supra 89+back light and tail light he helped me with my car ive been seeing alot of supras lately around long beach

A vacuum leak can also make it idle high too. A hissing sound can be heard under the hood if thats the case. The hose that comes loose for me is the T connection behind the intake manifold that goes to the cruise control and the heater valve. If those are OK double check under the intake manifold for the connections to the little canister and metal lines that wrap around the block. and go to the injector regulatorI have an NA so Im not sure about the turbo.
Here is a cygnus link that shows better than I can explain.

i might know what is wrong now i did another check and i got a code 51 i read that it could be the throttle sensor so im gunna try and go to the junk yard and get a new one i know the junk yard might have a defected one buh ill risk it ill just steal it sumhow...i replace the hose to the intake manifold with new silicone hoses from suprasport but ever since i replace it my check engine light comes up like earlier today around 11:30 were the light popped up and the car started to feel like it was gunna die...it would rev then jerk forward like it just lost all power buh it goes away

i think i have a few times but im not sure, and i dont think ive ever seen a gold and black top supra around long beach but ill keep my eyes open for it

yeah buh did u primer the rims. i still got the stock rims polish look to it

just plain flat black spray paint, used to be white, im thinking about primer black for the whole car with gold stock rims this summer cause im swapping my tranny from auto to manual hopefully this summer if i find a w58 bellhousing at millikan, i know the auto mechanics teacher well and he agreed to let me do it and might as well paint it since he got all the tools i need

nice how much did you get your manual tranny for. i thought about making my car primer black to but the stock paint still has the pin strips so i couldnt sand it down...i think im going to tear apart my motor this monday because i check my oil and its all milky and im gettin low engline coolant light again (yeah "hack" i think you were right) if im right im pretty sure they used stock head bolts when the old owner replace the HG. So ima have fun with my friends tearing it down and jackin parts from the junk yard lol..

Hey i know i asked earlier about the HKS bead MHG buh can a 1.2 bead MHG from them handle enough power..Thats if my car engine can use the MHG
Another thing i checked greddy and thye have a 1.0mm HG with a 83bore and 85 bore which one is better.

let me edit i bought the block tester and i will be testing the car as soon as possible

To answer the question is my head gasket blown or do i have cracks or leaks on my top or bottom block the answer is.....NO!!! Man im fuken happy as hell i did the test just about 4minutes ago and it stayd its blue color but i wont be a dumb ass and not replace the HG myself i will be saving for a new HG


Thanks IhateHack for all the help and i know i was the dumbass for taking so long to check it. Now im just wondering wha mods to do next..

next job is to replace the valve seals and washers i do have oil on my spark plug (5,6 plug)..n e clue where i can get a 14mm allen head though i tried sears and pepboys, autozone and napa still no luck

Take a 14mm bolt and 2 14mm nuts that fit the bolt. Lock the 2 nuts together on the bolt. Now use the head of the bolt as your allen head and use a 14mm deep socket to fit on the 2 nuts.

What were your compression #'s?

thanx ima do that

as for the compression im going to do that on monday when i replace the valves seals of course ima do it before so ill tell u on monday or maybe even today
let me edit that ill do it after i get the oil problem fix
