Default shaking out of 1st

i have a 96 sixer with a manual transmission and it seems like unless i rev it up pretty high when i take off in first gear my car usually shutters and shakes halfway through the shift process almost like it wants to stall. only first gear as soon as i am in gear it drives fine. my check engine light constantly goes on and off and i had autozone read it they said it was a emission problem and they could not tell me what was wrong. does this have anything to do with it or is it something to do with the clutch or transmission?

Just to let you know, they tend to be idiots. I had a guy read my check engine light, he looked up at me, and goes.."Do you know what that means?"

Lol. I will look into it for you bud.

I did some research, and this is what I found:

1. 99% of the time it's the Purge Flow Sensor. It is like $20 US. I think your better off changing that first. It is a black sensor with an electrical connector on it and two vacuum hoses going into it one from each end. It is on the passenger side close to the firewall. One hose comes from the vapor canister so that should help you find it or go buy it first so you know what your looking for. Don't forget to dissconnect your battery after to clear the codes. Good luck.

2. Ford P1443
This is the 3rd most common DTC. This code is described as “incorrect evaporative system purge control valve flow.” Ford’s purge flow sensor has been implicated as the source of the problem.

I hope that helps

found some more on it.

Ford On Board Diagnostics II, (OBD II) code P1443 means that the evaporative emissions charcoal canister purge sensor did not detect any flow when the canister should have been purging into the engine intake system. The purging, controlled by the computer,takes place when certain conditions are met, such as engine speed and temperature.What the computer operates to effect this purging is a 12 volt solenoid valve, solenoid means it has a moving piston in it which covers/uncovers ports in the valve so that flow does/does not take place. The "gunk" coming out of the charcoal canister will sometimes cause this piston to stick, resulting in purging not taking place when it should, the sensor in the purge hose detects this and sets a fault/trouble code and also turns on the "Check Engine" light. The electrical windings in these valves seldom fail, but anything is possible. To locate and check this valve, first find the charcoal canister, it will be a round or rectangular black plastic "box" with several different size hoses attached to it. If in doubt that you've found it, look at the bottom, there will be a plastic foam filter there---make sure it is not plugged up---. Once you've located the canister, start following the hoses attached to it. One will go towards the engine, follow that one along until you find the control valve that it attaches to, that's the valve that's not operating. Several things you can do now, just buy a new one and hope it is not the wiring or computer that's at fault. If you want to check it and the wiring, first, with key off, disconnect the two wire connector from it. Use a 12 volt test lamp, turn the key to "run" and check for current at both wires in the connector, one sould have current. Next, connect the test lamp between the two wires in the connector, start the engine and let it warm up, then run the engine up to around 1500 RPM or so, the test light should come on, if it doesn't, then it is the wire that was "cold" when you checked for power at the connector. or the computer. If the light comes on, then it is the valve. Remove it from the vehicle and clean it with an aerosol can of carburetor cleaner,use the "straw" that comes with the can and spray the cleaner into both hose nipples on the valve, alternatly spraying and shaking the valve. When you no longer get brown "gunk" coming out of the valve, reinstall it in the vehicle, but leave, if possible, the hose from the cannister disconnected. Start the car and let it warm up, (if need be), now raise the RPMs to 1500 or so. valve should now open and a vacuum should be present at the open nipple. If so, the problem is cured. On some OBD II equipped vehicles, repairing some problems will cause the computer to turn off the check engine light if the fault is no longer detected, other vehicles require that the computer be interfaced with and the code purged with a scan tool. Any questions, don't hesitate to ask. I'm curious as to what "Inspection Station" would not have sophisticated enough instrumentation to analyze the cause of a P1443 fault code.

Badcially i think it all boils down to you Purge flow sensor.

As for the shaky first gear, what rpms are you shifting at? Doesn't sound like a clutch problem from your first post.
