Hi there,

The tachometer of my truck has start to misread the actual RPM's of the engine, I haven't been able to connect it to any particular situation. Sometimes it works fine, others just misreads under the actual RPMs.

Has anybody heard or had this problem?

Thanks in advance!!!

What year is your truck?

 

Sorry, I have a 2004 with a 4.8L engine.

Hope to get some help...

Temo.
