so i have a 93 4wd pickup with a 22re engine.

i did some work on it recently and now it's running fine...downhill. uphill, it runs good but only in first gear...as soon as i shift into second it starts to splutter, buck and die...if i don't downshift again.

any help greatly appreciated.

 

check timing... what work did yoiu do??

 

Timing chain, the whole deal(guides, tensioner, etc...). Adjusted the valves, Welded an exhaust leak, and a new PCV valve.

i havent been able to get the timing perfect. for some reason no one has a timing light, even the local Napa dosent stock them anymore.

 

sounds like ECM is running in survival mode - check timing, wires, etc.

 

most likely a timing issue..

 

so i got my timing light in the mail today. set it to 5BTDC...it still is misfiring really bad.

 

hmm.. any reason you placed the timingchain? besides normal maintence?

 

it wasnt running to well before...and the chain had never been replaced.

i think it might be a fuel problem
my next step is to check the fuel filter and pressure regulator.
any other suggestions or ideas on what it could be?
