runs rough

[bryan_c_2005]

i have a 1996 s10 when starting the motor runs real rough at idle give it a lil gas seems to clear up a lil its like it is missing has new plugs and wires messed with the timing today pretty sure its on any clues what could be or should i check the timing again

 

[Jim Fairbanks]

Did it run rough before you put new wires on it?....Which engine do you have?...Sounds like it could be a vacuum leak.........could be the EGR valve leaking..not closing all the way.......Jim

its has the 2.2 no it did not run rough before the new wires ill have to check the egr thank you

 

[bob2]

from what im learning it could be a bad wire

 

[Jim Fairbanks]

Check to make sure the wires are on in the right order...pull one wire off at a time and see if there is a difference in the idle..if you find a bad wire there will be no change in the idle when you pull that wire off.....Jim

ill have to check that tomorrow when i get of work ill post back and let ya know what i find thanks also it is sucking in a lot of air through the intake would this be the cause ?

 

[Jim Fairbanks]

It could be..Try to find out if a hose or tube is loose or cracked causing a vacuum leak...Jim

 

[bryan_c_2005]

well i checked all wires spark plugs all seem good also couldn't find any vacuum leaks so i decided to check timing on it again it was of again i put it back and cranked a few times timing looked on so i just put the cover on to start it then took it back of and the timing was of again am i doing something wrong anyone know the cause or why it is doing this?

Check your distributor shaft and make sure the reluctor wheel does not move on it. Check for rust on it that could be moving changing your timing

 

[bryan_c_2005]

this is the 2.2 4 cyl it has coil pack

 

[Jim Fairbanks]

How are you trying to change the timing?...it is not adjustable....Here is what Alldata says........Notes

There is no "Set Timing Connector".
Timing is not adjustable.

NOTE : The Distributor is located in a fixed, non-adjustable position. No attempt should be made to adjust the engine base timing by rotating the distributor. Attempting to do so may result in engine cross-fire and mis-fire conditions.

i am just trying to line the marks on the timing gears with the tabs on the tensioner turn the motor over a few times like the haynes manuel there still lined up then i start it up for a few then checked the marks again and they was off just wondering if im doing something wrong there or if anyone know the cause of this
thanks for all the help

 

[bob2]

im not sure about this model but i have found myself messing things up when it was just on the exhaust stroke whitch makes the marks not line up. dont know if i explained that right. trust the pros

 

[bryan_c_2005]

just letting you guys know its fixed i was just second guessing myself on the timing just needed to take a break for a few lol but it was just a bent valve thank you all for your help

 

[Jim Fairbanks]

Glad you got it fixed...thanks for letting us know....Jim
