Car shakes like crazy and makes rpms stop

[AdrianSHO]

Hey guys I have basic bolt ons tune and meth kit I am having issues between 2k-3k rpms my car shakes like crazy and the rpms stops while it's shaking it's usually only a more harder throttle. Also I'm having more of a delayed throttle response as well! Please tell me if you guys have advice on what it might be or if you guys have experienced the same thing

When did you put on the meth, when did you get tuned for it, and how many revisions has Torrie done with the meth turned on?  Was the car running well before the meth was turned on?  Have you checked the PCM for codes?  Possibly the car shuts down and restarts (when tach goes to 0).

Usually it boils down to some issue with the meth installation/spray, so I would doublecheck that carefully.

It was about a year ago and yeah it was running good before and yeah they are generic codes that say cold timing over retarded bank 1

That would most likely be a VCT solenoid on Bank 1.  Sometimes it is a pin in the wiring loom that has come loose.  Hopefully that is as deep as the problem goes.

Is there a way of telling if it's gone bad

Its sometimes an intermittent issue which can be checked with a multi-meter and see if this helps any. Z

These are the codes

This is pointing to a wiring issue, p0020 being the cause and p0052 the result.  But if no short is found in the wiring to the solenoid, then likely the solenoid itself is at fault.
