I washed my engine and now it won't run right.

[Justin R. Lang]

I check the codes and this is what i got P026, P030, P052, P053, P098, No IPC Codes, No ACP Codes, No SIR Codes. What do these mean?
I dried the distributer cap and checked the pluges and wires. I washed the engine and that's when I started having problems. Do you have any ideas for me.

[DFBonnett]

You probably got water inside the cap. Take the cap off and dry the distributor internals and the inside of the cap with a hair dryer.

[Justin R. Lang]

I tried that already the cap was dry and clean I tried to dry it anyways but there was know change.

Disconnect the battery and give it a day to air out. You've probably caused something to short out somewhere.

Those are the codes and what they mean.

Try to dry out the ISC motor which is the black thing on the fro that has the steel piece that pushes on the throttle. Also try to dry out the TPS (throttle position sensor) on the back of the throttle body. I'd leave the cap off the distributor until you're sure it's dry inside, especially around the ignition module.

The trodel posisioning sencer was shorted out i put a new one on andnow it's back firing so i changed the distributer cap. but what is the firing order for it now i'm doing it one at a time so i'm not changing it at all, but it doesn't seem like it's right. in the front it's 1 3 5 7 but that doesn't seem right.
if you can hell me it will be valued in my eyes.

Facing the engine from the front, 2,4,6 and 8 are the rear bank from left to right.

The front bank from left to right as you face the engine are 1, 3, 5, and 7.

The firing order is 1-8-4-3-6-5-7-2

Number 1 on the cap is the first post to the right of that bulge on the coil cover where the wires plug in going counter clockwise . Number 8 is the next post going counter clockwise. Naturally, the rest fall in sequence.

You problem may actually be the adjustment of the TPS itself. The adjustment is a bit involved. After you get the firing order resolved, post back if you need the TPS adjustment procedure.

Also post the year and model.

[Justin R. Lang]

The firing order is set right now and yes I do still need the procdure to set the TPS. The make and model is a 94 cadillac sedan deville with a 4.9 PFI.

I also have a buddy of mine that locked his keys in his car it's a 95 ford thunderbird with the little keypad just below the driver door handle is there am override code to open the door. Or how can I find out it's oridgenal code or is it at all possible to do something like that.

I Thank You so much man You have helped me so much I can't even beggin to tell you. So one more time I say THANK YOU VERY MUCH.

Justin,
Loosen the two torx T-25 screws holding the TPS in place just enough so you can rotate it a bit but not so much that it can move by itself. That's why it has those elongated slots for the screws to provide for adjustment. Rotate it just enough to get a decent idle if you are having a problem.
There is a loose wire with a green connector near the alternator and near where the ISC harness plugs into the main wiring harness. Ground that connector to the engine block with another length of wire. I use a short length of wire with alligator clips on both ends
From the driver's seat start the engine. You will see on the display a Battery No Charge message. That's good because it means you grounded the alternator correctly. Get into diagnostics by simultaneously pressing and holding the OFF and Warmer buttons until the dash starts displaying codes. Then release. When PCM? comes up press the fan up button once. Then press the fan down button until you see PCM OVERRIDE. Press the up button again until you get to PS03. Now hold down the cooler button for about 10 seconds or so. The idle will slow because the computer is shutting off the idle control motor.
Leaving the engine running, open the hood and disconnect the wiring harness that goes to the idle control motor. The Idle Motor is now locked in the off mode.
Back in the car, press the OFF button. Now press the fan down button until you get to PCM DATA. Press the fan up button. You should be at PD01. Note the reading on the panel just to the left of PD01. It should be somewhere between -0.5 to +0.5, ideally 0. If the reading is not right, very carefully and slowly rotate the TPS a tiny bit one way or the other until it is. Someone in the seat reading the numbers while you adjust is a big help. Retighten the screws. Recheck the reading to make sure the TPS didn't move during tightening.
Shut down, remove the alternator ground and reconnect the ISC harness.
That should do it.
Can't help with your friend's lock. I know nothing about them.

I set tps and I sitll having problems.
When it warms up you can hit the gas and it won't move. it's like you didn't even hit the gas. the engin starts back firing but still stays running. if you keep your foot over the gas you can feel the pedal moving up and down. I think it has something to do with that other thing i had to disconect when I set the tps.
I got the TPS set at -0.2 that was as close as i could get it.
If you have anymore suggestions they would be onnered very much.

Does anyone want to buy a 1994 Cadillac sedan deville?Joke haha

[Justin R. Lang]

I got some codes again.
P026
P052
P098
I052

[DFBonnett]

Does it run any better if you disconnect the ISC motor where it connects to the main harness?

"I think it has something to do with that other thing I had to disconnect when I set the tps."

That would be the ISC motor. That may have shorted out, hence the suggestion to disconnect it to see if the problem improves.

The-.2 TPS reading should be fine. That was as close as I could get, too. The range is -0.5 to +0.5.

Double check the firing order.

Was it backfiring before you installed the new TPS?

[Justin R. Lang]

I'm sorry I may have mixxed up the ISC with the cruise control moter. Can you explane where the ISC is? If I did mix it up could I have messed up something when I set the TPS?
The Firing order Is correct. I thought of that and check it before I messaged you before.
It was backfiring before I changed the TPS.
Thank you for your help,
Justin R. Lang
