Hey guys,
having an issue with my s15 (sr20det).. no idea where to start :\ similar issues seen with skylines so yeah..
Car is choking while cruising, feels like its going to stall eventually. Was fine all week until Thurs night and then got progressively worse.
Seems worse at 60km/hr or low speed than 80km/hr. If I thrash it, it seems ok..? Maybe?
Maybe a related issue that has been going on for a few weeks is when braking to red light, sometimes the revs drop to about 200, cpl of times it has actually stalled on the freeway in heavy traffic/freeway carpark.
Have looked at every hose (I think), cannot see a vacuum hose off anywhere..
I thought AFM for the choking issue but swapped it yesterday with a friends and no difference.
Plugs were done a few months ago, pulled them out, they seem ok, asked 2 ppl for advice they said they look ok as well..
What else to check?
Another friend said o2 sensor but I think my fuel economy would be shit if it was that.
No idea when the fuel filter was last done as I haven't had this car long, would that be an issue?
Im thinking ignition or fuel at this point but not sure..
Thanks for any help
