92 q45 problem
92 q45 problem
just bought my Q and having some engine problem. it takes a while to get it to start when i crank it up. also when am just sitting on idle and gas it up, the rpm doesnt go pass 3000. i could use a little advice on this. by the way i just change all the plugs on it.

Mileage? Intake path condition? MAF connector?
And most importantly, timing chain guides?

Fixed rpm limits usually suggest an ecu in fail safe from lack of some sensor data.
Sometimes all the desired accelerator cable slack has been removed by a shade tree mechanic.
Coolant temperature sensor connectorcan increase idle rpm [cold warm up].
MAF or CAS [2 separate connectors] are the first places to wiggle and clean.
Whenever you purchase a used old Q expect to spend $3,000 [plus interior/exerior] quickly to replace the problems that caused it to be sold in the first place.
Have the plastic chain guides been replaced with updated steel units?
