rain stops jtd revving beyond 3500?
Hoping you might be able to solve a mystery for me...my jtd16v runs happily in the dry, no issues at all...however in the rain then the engine at some point refuses to rev beyond about 3500 rpm. If i turn the engine off and back on again it resets briefly but rattles a touch at higher rpm (more a feel than a noise).
Eventually when everything drys out then it goes back to running fine again. I've recently had the MAF replaced, the egr valve is working (i think?). The only fault code i have is for 'turbocharger boost sensor a circuit high'
Any ideas on where to start looking?
