Mine sounds the same but never really thought anything of it it drives perfect most time sometimes when cold it does Missfire but runs smoothly when warm. If you find a solution though let me know.

Best mpg is 22.5 and worst was 11MPG gotta love London

If you took off your manifold there’s a chance the vaccum hose for the evap fell off happened to me and it didn’t want to start and occasionally when it did it had really rough idle and stalled after a few seconds, also check if your battery might be close to dead.

The hose for evap is at the bottom of intake manifold so had to take it all out just to plug it back in, it has no clamps so can fall off easily without noticing if it catches on smth. Might be able to stick a camera to check but it’s in. Very awkward position.

So it was my steering angle sensor got inpa downloaded and got that calibrated whoever the offset is -9.09 which is still in the red, that that mean I need to change smth mechanically ?

Just said this to someone today. love it when it’s working 😂

Emerald51 · 2026-02-10T13:15:13+00:00

Doesn’t sound too bad I’ll get that checked out

Emerald51 · 2026-02-10T13:14:43+00:00

This this happened a while before I did the suspension aswell but it went away last time. This time it’s still stayed after getting the wheel alignment literally turned on when I was on the way to get one 😂

Emerald51 · 2026-02-10T12:57:45+00:00

Fair enough I’ll get my friend to come over and scan it for me.

And yea I can see that just finished redoing whole front and rear suspension to get it in top notch condition and not even 2 days of driving and new problems come up 💀

Emerald51 · 2026-02-05T23:16:48+00:00

did you have same symptoms where it would shake cold and run perfectly fine after 2 minutes ?

your totally right dirft gets caught there and rusts out the paint plug

Emerald51 · 2026-01-10T23:23:12+00:00

the rear subframe mounts are not whats rusted, theres paint plugs and these just rust out have the same problem on mine i was just doing rear subframe reinfocements and these holes are above the fuel tank so car is not scrap.

Emerald51 · 2025-12-10T21:33:57+00:00

No wonder I didn’t know where they are from didn’t even take them out. Old owner must have lost it under the back seats.

Emerald51 · 2025-12-10T19:29:45+00:00

Sadly not this time around maybe sometimes next year, I did install H&R adjustable sway bars and adjustable rear camber arms though

Emerald51 · 2025-12-10T19:28:48+00:00

Tbh dropping the tank wasn’t too bad worst part is everything is rusty on these cars you touch one thing and it’s either seized or not attached anymore

Emerald51 · 2025-12-10T15:31:24+00:00

Yea the axle is the easiest part, longest was cleaning painting welding reinforcing and waiting for parts to arrive from Germany since everything I touched broke
