The car started running rough, then started to stall out. I replaced the crankshaft position sensor, 02sensor, coil, spark plugs, wires, boot, timing belt, valve gasket on my 2004 Hyundai Santa Fe 4 cylinder 2wd. It ran fine for a few miles then it started acting up.. I would floor the accelerator and it would not go above 5mph, I wait a while and it goes up to 20 mph.. it will not go faster than 30 mph. The Tachometer stopped working just before some of these problems started. I am now getting a P0320 code and am being told I need to replace the ignition misfire sensor ($145). I'm on a tight budget and don't really want to start replacing expensive parts.

HI......
OK. just follow the number on the ignition coils.
And the number on the cylinders are.
The FIREWALL side are 1,3,5, Starting from the belts location.
The RADIATOR side are 2,4,6, Starting from the belts location.
The coil with number 1 go to cylinder 1. as the same way the rest of the coils and cylinders.

OK... I hope this solve your question .

THank you for use fixya.

Well I went ahead and took a go at changing the coils, plugs and wires yesterday. It literally took maybe 15 minutes and my hands didn't even get dirty. This is something that the auto place wanted to charge me 650 to do. I spent 200 on parts. I didn't realize the coils were the things sitting on top of the spark plugs. I think my 4 year old could've done it. All I had to do was unbolt the coils detach the wires and then replace. It was too simple.

check your computer next or look to see if you put the position sensor 180degrees out

P0320-is Ignition/Distributor engine speed input circuit. Inspect the wire harness and electrical plug ins in the area of the distributor. Replace the Ignition/Distributor engine speed sensor. This should clear up your Tachometer problem. Good Luck and happy new Year. From Ernie @ RedDeer, Alberta, Canada.

Each one of the codes indicate misfire, except p0320.

1. Check IG failure sensor (1) Connect IG failure sensor and PCM connector (2) Engine "ON" (3) Check that RPM meter on instrument panel is operating correctly and the signal waveform of IG failure sensor at terminal 4.

(4) Is the IG failure sensor normal? YES ??¶ Substitute with a known - good PCM and check for proper operation. If the problem is corrected, replace PCM and go to "Verification of Vehicle Repair" procedure. NO ??¶ Substitute with a known - good IG failure sensor and check for proper operation. If the problem

Testimonial: "looks like I had a bad IG sensor because I just drove it 10 miles and no check enigne klight. I will plug the old one in and see if it kicks a code."
