I had a starting issue on my 04 D2 with 183K. It would crank but not start for a while then slowly start like at zero RPMs. Looked on here and sounded like the CPS. So I bought a new one and installed it. When I was installing it I had to take the Y pipe off and I could not reach the clip enough to get it back on. Now that is back together I still have the same issue and now I have loss of acceleration. Once i get up to 70 MPH it runs OK but no power. Idle is OK. Any ideas? MAF? I put a new Power steering pump and lines on as well....That works like a champ! I do get error codes...OBO P0134, P0135, P0154 and P0155. O2 sensors all four but would that cause the power loss? Hope some can help..Thanks in advance.

 

 

I am wondering is you truck loosing power on acceleration ?

 

I bought a new cps and the truck ran worse also. I bought a used one from the upullit for $3 I think just to try it and the truck ran perfect. Its hit or miss with cps sometimes. I keep a spare on hand.

 

Ugh really.... spent like $60 on a good one... I guess I can try putting on a cheap one. Would the CPS make the truck not have power on acceleration? This is what I have done new power steering pump and lines I also put on a new Throttle body heater plate as the old one was leaking. I did clean the inside with brake cleaner. I noticed that there was a sensor in it could that be why I don't have power on acceleration? After I did that I replaced the CPS because the truck was not starting right. Maybe I did not need the CPS at all??? HELP :-(

 

Why did you have to take off the y pipe?

 

My fat hands could not reach the CPS clip to get it off the harness clip. Just made it easier to work on. A few videos showed that taking the Y pipe off made it easier to work on.

 

I think you should try to explain your problem a little better.

do you have rpms but no speed? Acceleration is slow?
Are you missing?
Any check engine lights?

 

2004 D2 183K.
1. Starts and idles fine.
2. When I accelerate no power RPMs do not go up until you feather the gas peddle.
3. can get it on the highway up to 70 but takes a long time getting there. No power
4.Check engine lights are p0135, p0134, p0154 and p0155 all four O2 sensors. But that should have nothing to do with acceleration right?

I did clean the throttle body housing with break cleaner when I put on the new Throttle body heater plate and I see that it has a sensor on it. Wondering if I killed that sensor.
