Crown Victoria Performance

:banghead: I just got a crown victoria 1998 P71 , I made some modifications on it but I did not like the results, first I put a K&N filter upgraded MAF tube for more air flow, I took the tip of the air filter housing that looks like a cone I drove it and it ran weak like if it needed more fuel I lost that quick throttle response so I put back the stock MAF tube back because the air meter was not detecting enough air flow the air has to go through with pressure , before I did that mod the tires will skid around 15-20 from a complete stop to full throttle not brake torching, I lost that that quick throttle response, then I installed a chip module mod and removed my catalytic converters and replace them with 22inch glass packs-pipes to improve exhaust flow and reduce the rattling noise the mufflers makes after all these modifications all of a sudden my transmission started acting up it works fine 1-2 gears but for third gear it RPM's more and the car advances slower than normal, I have worked on my own cars but this is my first electronic control transmission car I was thinking the tranny is giving up but the mechanic said the tranny is fine that it has to do something with a sensor or reprogram and the only sensors that could be affected by these MOD's were the ATS, MAF and the four oxygen sensors :banghead: my next upgrades were going to be a 75mm throttle body and 3.73 gears but I need to get this fix any ideas, tips will help. :uhoh:

For the trans problems, when you do some upgrades, you may need to do a quick learn test to reprogram the transmission. The upgrades you were talking about should require a quick learn test but you may want to look into it. You should search the proper procedures for a quick learn online, because it is a somewhat long procedure. Try that and see if it is still acting up.

I was thinking and thinking :uhoh: it has to be something I change or install that made the difference but I just did not want to believe everything I did to my car was done to improve performance I was about to give up and sell the car but I took my friends advise "TAKE THE DAM CHIP OFF" and I just did like a couple hours ago and test drive my car on the freeway WOW it seems everything went back to normal it looks like the chip was effecting the transmission I hope that was the problem because if it was I saved lot's of $$$$$$ :naughty:

what kind of chip did you get?

It is the chip module that you put on the ATS=AIR TEMPRETURE SENSOR I got it from ebay the brand is REDLINE I'm going to have to return it for a full refund I decided to go with SUPERCHIPS programmer it will de great for the gear change.

is it a superchups custom tuner or the regular 1725 tuner?

you will need to get a different speedo gear to make your speedo work properly again.

It is a Ford - Max MicroTuner for Cars part# 1725 which I think is the regular by the way were can I get another speedo gear.

Clicky (http://www.crownvic.net/liquid/speedo_gear.html)

you can buy the speedo gear at any ford dealer... maybe even ebay.

I was about to buy a speedo gear and I heard that the speedo gear I need is not recommended because it has a reputation of grinding and breaking its teeth.

is it the white speedo gear that you need?

i have heard that from a few people. i know some people that have some major power running through there cars and they need to change the speedo gear at every oil change.

Yes that's the one I need, I don't even want to give it a try I will just stick with the stock one

i would still replace it and give it a try. the people that were having problems with the gear were running a lot more power than your car. they are not expensive.

if you want ro run a bigger maf you will need a custom tune, not the 1725

Well custom tunning will be the best, I was searching for crown victoria in the internet and this is what I found a TRITON V10 CROWN VICTORIA, great way to get HP:thumbsup: I WILL LIKE TO DO THIS PROJECT ONE DAY
