I just installed my injen CAI and took the car out for a test drive and the check engine light came on, then the O/D light started flashing. But most important, the shift from 1st to second gear is terrible, it jolts the whole car, 2nd to 3rd isn't as bad, but the first shift is a major problem, any suggestions?

check what code it is, ur trans may have something worng with the o/d light flashin do the trans diagnostic.... i dunno how to as i have a 5 spd.... check all ur vacuum lines, make sure the intake isn't pinching anything, and all the hoses are not bein squeezed

I don't know how to do the trans diagnostic or check the code, please help
the lines look ok

put ur car on the acc position, get to the ecu and turn the screw on it all the way to the right, wait two seconds, then back to the left, and then come back up and ur CEL should be flashing the fast blink is each number like if it goes blink blink blink (thats 3) then pause and then blink blink blink blink (thats 4) ur code would be 0304 ... im not sure about the auto tranny diagnostic

thanks for the input, any other suggestions, I know my tranny was in good condition when I did the install

did u disconnect ure battery before pulling the maf sensor?

sblax2000

yeah the battery was out of the car for over an hour, would that affect the shifting, it feels and sounds horrible shifting to 2nd

check if there's any air leaking from ur throttle > pcv > intake pipe > filter

where is the ECU to check for codes?

Sounds like you disconnected the dropping resistor. It's mounted on the inner fender wall by the air box. Chances are if you were playing over there you probably knocked one of the leads off that resistor.

That will help you with the ECU ?'s.

First do this:

AT diagnostic
__________________________________________________ ________________

95-97
1. Start engine and warm to normal operating temp with O/D off.
2. Turn ignition swith to off postiton wait 5 sec.
3. Turn ignition switch to the ACC position.
4. Put O/D to ON.
5. Move shifter to P, turn ignition on but don't start engine.
6. The OD light should come on for about 2 secs.
a. if light does not come on somthing is wrong with the trans. computer.
b. if light comes on proceed to no 7.
7. Turn ignigton key to off.
8. Turn ignition key to on, don't start engnie.
9. Move shift lever to D, trun ignition to off.
10. Put O/D switch to off position.
11. Turn ignition off.
12. Put O/D to off, turn ignition ON wait 2sec and move shifter to the 2 position.
13. Put O/D to on, move shifter to 1 position.
14. Put O/D to off, depress accelerator all the way to floor and release.
15. The computer is now in output mode and will start displaying the codes.



There’s one long flash that signifies the start of the sequence. Following
should be 10 short flashes. Then it
repeats.
Remember the first long flash indcates the start of the sequence followed by
10.

All 10 flashes the same = No error codes read at this time
1st flash longer than others = Revolution sensor is shorted or disconnected.
2nd flash longer than others = Speed sensor circuit is shorted or disconnected.
3rd flash longer than others = Throttle sensor circuit is shorted or
disconnected.
4th flash longer than others = Shift solenoid “A” circuit is shorted or
disconnected
5th flash longer than others = Shift solenoid “B” circuit is shorted or
disconnected
6th flash longer than others = Overrun clutch solenoid circuit is shorted or
disconnected
7th flash longer than others = Lock-up solenoid circuit is shorted or
disconnected
8th flash longer than others = Fluid temperature sensor is disconnected or A/T
control unit power source
circuit is damaged.
9th flash longer than others = Engine revolution signal circuit is shorted or
disconnected
10th flash longer than others = Line pressure solenoid circuit is shorted or
disconnected

All the same with no long start flash = Battery low, been disconnected, or
control unit has just been
reconnected.

I think njmaxseltd was right, the wires in my car are not long enough to reach the MAF and also to plug into that smaller grey plug on the back wall near the air temp sensor on the stock air box. That piece was unplugged as he said. So now I don't know what to do, the wire connecting to the MAF sensor needs to be longer, how do I fix that?

Check the wires and see if there's something holding the wires up.

there's a lot of electrical tape around them, I don't know much about wiring at all though. but the wire is about 4 inches short, can I make it longer or should I unwrap the wires and find an alternative?
