Help me!!!

[95SHO420]

My name is Matt. I'm 20. I just bought my dream car the one i've wanted for a very long time. My '95 3.2 SHO. Bought it extremely clean. No major issues, so i thought. So i bought a OBDI scanner, ran some codes, and came up with a bunch of stuff i need help on that no one else has been able to help me with. Hopefully you guys can! The code list ran as listed below:

O2 sens. Bank 1, Bank 2. = Easy fix.

EGR flow - DPFE.

Trans Range Voltage.

NOW for what my car is doing...



I will start my car up, cranks up fine, no problems. I'll drive exactly 2.2 miles and the CE light comes on. After about 5 or 6 miles, if i stop, my car will start to bog out around 300 RPMs, or so. My guess is that the EGR flow isn't letting the engine run the way it should be. Maybe the DPFE is making it cut off. Maybe its the O2 sensors. WHO KNOWS I DON'T! Now when i first start up and drive down my road, in 1st gear it will **** into 2nd real hard. and after it does it that first time after that it doesnt do it. unless i turn the car off for about 20-30 minutes. Someone please help me idk what the **** is going on i just want her to stay running!

Change the DPFE,only 4 small bolts n a plug,clean the MAF, and the IAC

What were the actual codes? (the numbers, not the descriptions)

 

[95SHO420]

hold on let me go find the sheet. and i cleaned the DPFE with carburetor cleaner and OHS cleaner. same problems.

 

[frosho]

Could be blocked EGR ports in the intake. Here's a write-up for cleaning them out - Check Engine Light with EGR Error Code

 

[95SHO420]

codes were 171, 172, 173, 182, 183, 335, 336, 542, 543, and i cant remember the 600 code but it was in the 600's and it said Trans Range Voltage.

 

[frosho]

I'd swap in new O2's, a new DPFE, clean out the EGR ports, and then see where you're at.

Do you need a replacement DPFE? I have an used one if you want to private message me an offer.

 

[95SHO420]

cant i just clean my DPFE? and i have a couple other questions. i wanna know if anyone knows why my damn car keeps cutting off everytime i stop it. at every other red light my car will bog out, i can put it in neutral and it will stop(most of the time) but as soon as i put it back in drive it cuts off. im not driving it hard and im not dogging it. im running 93 in it like im supposed to, keeping up with fluids, and also i wanna know about the tranny if anyone else when they bought theirs (if automatic) has had their car **** into 2nd from 1st gear.

DPFE wont make the car run bad. A stuck open EGR will though. You can block the EGR off with a piece of soda can to check that.

I'd clear the codes and see which ones come back. That could narrow it down a few.

That trans code probably has a lot to do with that. See if you can get the code again and post it. My guess is a bad/improperly adjusted MLPS (transmission range sensor).

 

[95SHO420]

the code was Trans Range Voltage...and no one has yet to discover what the **** that code means, or what it pertains to. must be a bunch of ******* mechanics around here in north carolina.... :/

 

[Bob Gervais]

Or too much 420'ing.

If you can get the code number, that will help us help you.
