This winter I ported the plenum and when I got the car out this year it has been running bad, well the injectors seemed to help with the MAJORITY of it.

But the car still is lacking a little power. I do not have the ability to break the tires loose on demand like I did last year.

Anyone think I could have messed up porting?? any other suggestions (Tune up is all new this year cap, rotor, plugs AC, Wires AC, coil) Sunday I go through replace IAT sensor that was left in during porting that may be messed up, reset IAC, set TPS again, check FP, what else?

I have pictures

 

If all you did is remove the humps in the plenum floor behind the throttle body, that should not have created any problems.

If the runners were removed, and gaskets replaced, you need to verify that there are no leaks at any of the six flanged joints.

 

Did your battery go dead over the winter? If so your computer will need to adjust. I think it takes 10-20 starts to complete this. I disconected my battery over the winter. It wasnt 100% for about a week.

 

grinding those humps out is HARDLY porting. Are you kidding, you probably increased airflow by about 1%. This is certainly not enough to cause any problems. Your problem is elsewhere.

 

Battery was OUT all winter, And last winter too with out this kind of problem.

I tried to reset the IAC and the car wouldnt even start, I had to force it to start and it has run like crap eversince. I did re-reset the IAC and I havent had the chance to take it out yet. TV cable was not right and that made it a little better.

I am getting a MID throttle stumbling, minimum throttle and full throttle are fine the mid range is terrible.

New tune up coil nad injectors.

 

did you change the filter for the fuel system when you did injectors? know it's a dumb thing, but gotta cover the bases.

 

Not this year but within 4k miles. I will put that on the list of quickies and cheapies.

 

Oh. NOW we get the whole story. You hadn't mentioned earlier that you changed injectors. What injectors? Did you change the injector flow? Reprogram?

 

Well it has been bad even before injectors, it is since I brought it out from storage.

I put in the Ford SVO 22lbs I didnt think anything needed to be changed.

Any suggestions?
