This cars got so many problems but im so close. it hasnt seen the road in 5 years untill yesterday and today. The motor runs really really weak. i know it has spark because it arched when i pulled each wire . i changed the middle coil pack too. Im going to try to run a paper clip test tomorrow. The computer screen says check fuel. Could it be a bad fuel regulator? sensors? Clogged cat? Injectors? EGR? ICM? It takes so long to get up to 40 mph. Tach reads 1800 at idle and idles bad. Also, the heads up speedo says around 35 when the dash speedo says around 50.... soo many bugs need to be fixed.
maybe the gas is bad?
vacuum leaks?
CK Fuel means you are low on gas. If you have lots of gas, try reseting your fuel economy and avg speed readouts on your DIC. The dash speedo is a common issue, try to find one on ebay that reads more accurately. What condition is the crossover pipe in, is it original?
Yea the crossover is original but isnt leaking. Im going to get new injectors and test the fuel pressure. The flash code said code 13 which is O2 sensor and i replaced that today, unhooked the battery , ran it and no more code 13. I also need to replace the egr gasket and the vacuum hose was unhooked. With new plugs , i got it to idle down to 1500 today which is best its ever run. Im still positive the injectors are shot....tick tick tick tick. We'll see what tomorrow brings. thanks
bosch o2?
yea bosch O2. today im going to test fuel pressure. t
Everyone else will prolly agree with me, and I can vouch: Bosch O2 sensors are the worst waste of money. I've gone through FOUR (4) of them in the past year before I learned my lesson. Trust me when I say it's worth spending the extra money to get the $60 one from the GM Dealership. AC Delco, I beleive? It's much better, and I have no reason to replace it. Bosch kinda sucks on the O2 sensor side, as far as I'm concerned. My .02
UPDATE> I finally checked the fuel pressure today and it was around 44 psi which is normal. I still cant understand how the thing is so slow. I mean slow... You could pass me in a golf cart slow. I changed the rest of the coil packs today too. The car had alot of varnish in the gas tank before i replaced it because the gas was about 4 years old. Could clogged Injectors and clogged cat make this car run that slow? Has anyone had a similar problem with injectors?
run some injector cleaner and see if that helps. what wires are you running for spark?
ive got stock wires i think.
