Hi all,thanks for reading!
On way bk from Wk last nite,come out of a roundabout n went to take off in 2nd,got to between 4-5000 revs n started juddering a lot! Eased off then tried again on next r/b n it was the same thing in 2nd n 3rd aswell,got bk n read the faults codes as bein
21 engine coolant sensor
24 idle air
33 speed sensor
Checked n cleaned connections,all seems fine now n the check engine light is off?
Shall I put it down to car havin it's time of the month? Or start lookin for something bigger? Car is 94 wrx import

 

I'd say drive on for time being and see if fault re occurs.

21 + 24 could be interlinked as if one is up the swan then it could affect the other
