Hey guys I'm in need of some type of answers please .. I have an appointment On Monday for Toyota to diagnose my engine. In order for them to check compression can it be done by their computer or do they need to remove my upper intake manifold? Which is a lot of labor. I don't know what to do I feel like I have a bad injector


Car is struggling to accelerate quick the rpm skips up (chokes) between 1 and 2 thousand rpm instead of going up smooth and quick , same as if I wanted to press the pedal from 2 thousand rpms to 3 thousand it should only take a slight press on the gas to kick up .. Also from stop or roll if you hit the gas slightly harder than soft. It will make a loud pop /crack from under the pedals. from my experience driving it until now each gear had 3 notches where a push on the gas would kick up ,,the last notch is 4 thousand plus ... I'm not a mechanic but I know the feeling of my rpms and how easy it was
Before compared to now .....

Some one please send me some

Do you have CEL if so what are the codes?

I can't recall but I believe your intake plenum is metal correct? If so they probably won't have to take if off in order to check the rear cylinder compression. However, thats the short cut the technician will take. They'll still charge you for the same amount of time it states in the book.

Only cel code is for bank 1 sensor 1 o2 sensor , and I've changed the cat but the code came back I haven't changed the sensor, reason why I changed it is because I bought it with the same cel code for the cat and drove it from 174k to 179900 is when I started getting this issue 2 days after my dad put in gumout high mileage fuel injector cleaner in my tank for no reason he wanted to argue and make me put it in .. 2 days later the car was really choky. Even in higher rpms so I changed the cat now it's only between 1-2 thousand rpms but it feels as if it still has a loss of slight power with the gas pedal and rpm levels some times I'll slight tap it will move a cm I have to tap it again a little harder for it to move up

Po135 I haven't re connected it since the cat swap but the engine was misfiring or choking before I changed the cat and it didn't pop up any codes then only the p0135

Ps here's the new parts I've done

All three engine mounts

The front exhaust pipe w flex pipe and cat

All new spark plugs and wires

The pcv valve I did my self the above was done by a
shady mechanic who
Charged 280 for the labor
Also cleaned the throttle body my self
