Last night as I took my car out for a drive (after it been sitting for a whole month) and noticed a heatshield style vibration coming from where the Carsound Cat is . Only when it is cold though...when the car is heated up for about 15-20 min. the noise starts to gradually go away and get quieter and quieter.

The second problem I noticed was when the car is cold..and slightly warmed up...
I try to give it Steady throttle at about 18-2200 ..and when I try to keep it at those rpms..the motor starts to fluxuate the rpms from 1800-1000 back and forth.

However when the motor is FULLY warmed up..that problem goes away and has no problem keeping a steady throttle at 1800-2200

NOW this is the problem that occurs when the motor is fully warmed up..When I shift from 1st to second or 3rd...at around 4k rpms ..the motor lags really bad..as if the e brake was on.

Wth do you think it could be? A faulty sensor ? Clogged cat?

I not getting check engine light..so I cant check for any codes


Any of you guys experience this problem and can help a brother out

Thanks

 

I guess I'm the only one that had these weird problems

 

have you checked the usual items like plugs, plug wires, distributor, alternator...

if your thinking faulty sensor they usually throw up codes.

maybe its cuz thanh boosted that motor when he had it before it went into the car that you now own... jk

 

When was the last time you changed the fuel filter?
