You really only have 1 choice here if you are intending to do the repairs yourself. You require a scanning tool to access any error codes that your engine has thrown. The check engine light coming on tells you that there is a problem, Ifthe lightdoesn't go away by the 3-4th. time you've run it after it first came on there is a problem. If you got the proper scan tool, follow the directions. If you don't have a scan tool there is a connector somewhere under the dash and by jumpering the proper 2terminals the check engine light will flash a code (codes) which will be a 2 digit numberthat will tell you where the problem is. The jumper thing is quite easy to do...search the site, i'm surethere's a tutorialhere somewhere. When you get the codes, come back here and do a search for error code definitions....once you know the problem we might be able to help.

 

u can take it to a local parts store like a autozone and they will scan it for u for free.

 

I doubt he has an AutoZone in Norway....

 

A first gen can be scanned with a paperclip.

haha sry totally missed that. well maybe the have a parts store there that does free scans. but ya neon71665's link is very useful

 

im having a similair problem, my fuel injectors dont get soaked though.... i tried doing the paper clip thing. no dice. i went to autozone and scanned it no codes. i went to a mehcanic and he scanned it with one of those fancy snap on scanners. didnt return any codes. i did read the computer however.
one other thing with mine is when it starts sputtering at ide the check engine light will blink in time with the sputters.
the engine will also surge occasionally when idling.
on one occasion i had a complete loss of power then had a backfire but it wasnt from the back or the engine bay it came from the bottom of the truck. also the engine bay fills up with exhaust real bad. to the point you can see it comping from the vents by the windshield wipers. the exhuast also flows out of the wheel well by the passenger side front tire sometimes when i stop. i think i have a leak in my exhaust somewhere but i havnt been able to track it down. and if its the catalytic converter i have no idea becuase i dont smell a rotten egg smell... if i smell anything it smells like its running to rich. becuase the ehuast has a distinct gas oder to it.
