When I'm driving down the road, the engine surges and then bogs down and I
notice that the odometer increased by 10 mpg or so, but the speed doesn't
increase. Sometimes the engine will quit running. Are there any ideas what
could be causing this? I'm really hoping it's not my transmission.
On cold mornings the check engine light comes on when I first start the
engine. It runs for a couple of seconds and then quits. I keep trying to
start it until it starts without the check engine. The other night it took 5
times to start and keep running. I noticed a strong smell of gas at that
time. My OBD-1 connector is a 12 pin connector, but it doesn't have a wire
going to the B position (diagnostic terminal). Someone said I have something
in between OBD-01 and OBD-2 so I can't short A and B together to make the
Check Engine Light Flash to get codes. I don't know anyone with an OBD-1
scanner or have the money to pay someone to do it right now.
I replaced the spark plugs and wires. When I compared the plugs that I took
out to the photos in the Chilton manual, it read that they had been in too
long because the gap had increased to 0.09 in. They were a brownish white
I found some bad vacuum hoses and replaced them. I have a vacuum pump that I
used to check to make sure I can create a vacuum going to different
components. This is what I found:
1. The vacuum hose going to the Transmission does not leak.
2. The vacuum hose going to the Evaporative Canister Purge Valve leaks
3. The vacuum hose going to the Evaporative Canister does not hold a vacuum
4. The vacuum hose going to the Fuel Pressure Regulator does not leak.
The only thing that I haven't checked for vacuum leaks is the Cruise
Control. I have to remove components that are on top of it to see what
condition the vacuum hose is in and where it goes.
If someone has any ideas on what else to check or knows what is going on I
would really appreciate some help.
Thanks in advance,
