Did you replace the Spark plugs and wires lately? What about the motor mounts?

385

Yup I did sparke plugs, wires, and the rotor in the distributor cap as well when I did the tune up about 3 months ago. And for the motor mounts she is in need for some new one.

Check vacuum lines and EGR. Do you have a check engine light? I'd run some injector cleaner first before messing with the injectors. Did you clean the IAC and throttle body yet? the MAF?

385

The EGR is blowing out air. The IAC and throttle body I did not clean yet gonna do that this weekend. The MAF I did clean when I put the intake on. And as for the cheack engine light it does come on but only when I'm driving never in idal. But I didn't see a catalytic converter when I first bougt the car I thought that was maybe why the cheack engine light comes on.

If the EGR is blowing air as you say, that is your issue. Have the codes pulled so you know what your dealing with, Autozone will do it for free, post back the numbers.

Autozone doesn't do it any more but they sell the reader. I can do it my self rite I just have to decode what codes pop up rite?

I have a 92 t-bird 5.0HO, i had a similar problem and finally found what was wrong. It was the harmonic balancer the whole time. Changed just about everything, and it got so bad , it broke into two pieces. I had no idea its two pieces put together. It could be ready to break. If you cant find ur problem , you might want to check yours. They do wearout.
