 | code 32 is a EGR Loop Error. the books says this happens when is "sees" improper vacuum. so I would say you have a stuck EGR vavle or a vacuum leak or both but start there |

| Was this one with the solenoid for the EGR ? Egr may be only dirty and need to be cleaned. If you do have to replace it be careful of the differing types that look similar. I would think about using the dealership to avoid the wrong size orifice problems that seem to crop up from national chain stores. |

| If it is infact a vacuum problem, I would also look at the little hose that runs into it. Being small, it can also be very brittle. Happens with age. If there is a small crack in the line, then a small leak could lead to it reading an inpropper vacuum.

| so did you look at your EGR valve yet? it only has 2 bolts and very easy to take off and if your careful you can re-use the gasket. Try cleaning the EGR valve like Cabtruck said. have you changed your fuel filter lately? cheap part huge performace monkey wrench when it starts to go |

| the surge is probably a b/o egr valve, a weak spring in the valve causes it to open too much at low speeds/low throttle. was screw in that hose? |
