98 neon HLP

[robotman1969]

Ok i have a 1998 neon SOHC idles great but maybe high will put away at idle..... but as soon as i step on the gas it boggs ..... and when i put it into gear it runs rough and boggs even more when i step on the gas no pwer .... no speed ..... runs very rich ...... new plugs ,wires, coil pack , pcm , camshaft sencer , cleaned intake body , ........ help .... lost what to do now .......
also the cel is on but dont have a code reader so not shore what code it is......

[Bear]

For codes, with engine off turn key to on (not start) then off, then on, then off, then on and wait. The CEL will flash, count the flashes (like 0ne flash a pause, two flashes and a longer pause) this is code 12. Tell us what you get ( code 55 is end of coding test).

Try a can of water out, HEET, Dry Gas, etc in the tank, condensation will give you the symptoms you describe.

thanks guys .......... there r no codes ......would a pluged converter do it to ?.....i tried that it also back fires a little on decel. .............. also canged oil as it was loaded with gas ......... resealed intake manafold also cleaned good when it was off .......... did notce one thing runs beter cool ......... but still boggs as soon as the gas is pushed .....and no power hard to the floor at take off to get it up to 20 kms

I would expect the symptoms your car has if the timing was 'off'; such as if the camshaft was off one tooth from being properly lined with the crankshaft at top dead center. It isnt easy to check this, but its what I would try doing next. The camshaft position sensor only gets its info by 'learning' the correct crankshaft-to-camshaft position after you have disconnected the battery. If the cam timing was off when the battery was reconnected, the PCM would never know it - so there would be no code.

one of the first things i did was go right gor the belt ..... it was bang on ...... and i already replaced the camshaft sencer and the plug end ..... and i just replaced the trany fluid and filter ......... still no pick up ...... but im finly getting a code 51 in the book i have from the old cars thats a o2 is to low ..... is that still right for the 98 ?

[Bear]

Code 51 is still an O2 issue, but can't say if it is upstream or downstream sensor. Go to Auto Zone and have then code for free and see if their scanner can isolate which sensor.

[robotman1969]

well my book reads as follows ..... 51 O2 singnal stays below center ( lean ) ....... and right by the O2 after the converter there is a big kink in the pipe i saw to day ............... would that give me my bogg down problem .......... and power lose ?

[Bear]

If the exhaust pipe is pinched it will definitely cause a power loss.

also unplugging egr solenoid wires dose not give me a code there is power and ground to plug dose this mean the solenoid is bad ....egr is working will move when i aply vacum will this also cause my problem but the hose on the EGR is plugged solid ... so i on plugged it ???? also how much of a kink would it take to give me my problem ..... becuse after closely looking at it today it is not that closed off .... but it is kinked some ?

its like the timeing is off but only in gear ....... is there a knock sensor on this car ..... if so where ... and would the retard the time enough to do this ?
